Vanadium Chemical Properties,Uses,Production
Description
Vanadium was discovered in 1830 in Mexico by Andreas Manuel del Rio. It is present at 0.01% in earth’s crust and found in about 65 different minerals. Vanadium is released naturally into the air through the formation of continental dust, marine aerosols, and volcanic emissions. The natural release of vanadium into water and soils occurs primarily as a result of weathering of rocks and soil erosion. Anthropogenic sources include the combustion of fossil fuels, particularly residual fuel oils, which constitute the single largest overall release of vanadium into the atmosphere. Deposition of atmospheric vanadium is also an important source both near and far from industrial plants burning residual fuel oils rich in vanadium. Other anthropogenic sources include leachates from mining tailings, vanadium-enriched slag heaps, municipal sewage sludge, and certain fertilizers. Natural releases to water and soil are far greater overall than anthropogenic releases to the atmosphere.
Chemical Properties
Vanadium is a soft, ductile, silver-gray metal. It has good resistance to corrosion by alkalis, sulfuric and hydrochloric acid, and salt water. Vanadium metal, sheet, strip, foil, bar, wire, and tubing are used in industries. It is used in high-temperature service, in the production of rust-resistant, high-speed tools, and is an important carbide stabilizer in making steels. In fact, most vanadium is used as an additive to improve steels. Vanadium steel is especially strong and hard, with improved resistance to shock. Vanadium pentoxide (V2O5) is perhaps vanadium’s most useful compound. It is used as a mordant—a material that permanently fi xes dyes to fabrics. Vanadium pentoxide is used as a catalyst in chemical reactions and in the manufacture of ceramics. Vanadium pentoxide can also be mixed with gallium to form superconductive magnets.
Physical properties
Vanadium is a silvery whitish-gray metal that is somewhat heavier than aluminum, butlighter than iron. It is ductile and can be worked into various shapes. It is like other transitionmetals in the way that some electrons from the next-to-outermost shell can bond with otherelements. Vanadium forms many complicated compounds as a result of variable valences. Thisattribute is responsible for the four oxidation states of its ions that enable it to combine withmost nonmetals and to at times even act as a nonmetal. Vanadium’s melting point is 1890°C,its boiling point is 3380°C, and its density is 6.11 g/cm3.
Isotopes
There are 27 isotopes of vanadium. Only vanadium-51 is stable and makes up99.75% of the total vanadium on Earth. The other 0.25% of the vanadium found onEarth is from the radioisotope vanadium-50, which has such a lon+17years that it is considered stable. The other radioactive isotopes have half-lives rangingfrom 150 nanoseconds to one year.
Origin of Name
Named after the Scandinavian mythological goddess Vanadis because of the many colors exhibited by vanadium’s compounds.
Occurrence
Vanadium is not found in its pure state. Small amounts of vanadium can be found inphosphate rocks and some iron ores. Most of it is recovered from two minerals: vanadinite,which is a compound of lead and chlorine plus some vanadium oxide, and carnotite, a mineral containing uranium, potassium, and an oxide of vanadium. Because of its four oxidationstates and its ability to act as both a metal and a nonmetal, vanadium is known to chemicallycombine with over 55 different elements.Vanadium’s principal ores are roscoelite, patronite, vanadinite, and carnotite, which arefound in the states of Idaho, Montana, Arkansas, and Arizona as well as in Mexico and Peru.It is also a by-product from the production of phosphate ores.
Characteristics
Vanadium is an excellent alloy metal with iron that produces hard, strong, corrosion-resistant steel that resists most acids and alkali. It is even more resistant to seawater corrosion thanis stainless steel. Vanadium is difficult to prepare in a pure form in large amounts. Impureforms seem to work as well as a very pure form of the metal when used as an alloy. Whenworked as a metal, it must be heated in an inert atmosphere because it will readily oxidize.
Uses
The major use of vanadium is as an alloying metal to make a strong and corrosion-resistant form of steel that is well suited for structures such as nuclear reactors. It does not absorbneutrons or become “stretched” by heat and stress, as does normal stainless steel, thus makingvanadium ideal for the construction of nuclear reactors.Some of its compounds, particularly the oxides, are used in chemical industries as catalyststo speed up organic chemical reactions. The yellow-brown vanadium pentoxide (V2O5) is usedas a catalyst to facilitate the production of sulfuric acid by the contact process. Vanadium pentoxide is also used as a photographic developer, to dye textiles, and in the production of artificialrubber. When combined with glass, it acts as a filter against ultraviolet rays from sunlight.
Definition
A silvery transition element occurring in complex ores in small quantities. It is used in alloy steels. Vanadium forms compounds with oxidation states +5, +4, +3, and +2. It forms colored ions. Symbol: V; m.p. 1890°C; b.p. 3380°C; r.d. 6.1 (20°C); p.n. 23; r.a.m. 50.94.
Air & Water Reactions
Not oxidized by air and not appreciably affected by moisture at ordinary temperatures. Some hydrogen gas may be created however this would proceed slowly under ambient conditions. Insoluble in water.
Reactivity Profile
VANADIUM is a reducing agent. Finely divided form favors rapid or explosive reactions with oxidizing agents such as air or oxygen. Reacts exothermically with compounds having active hydrogen atoms (such as acids and water) to form flammable hydrogen gas and caustic products. The reactions are much less vigorous than the similar reactions of alkali metals. Can catalyze polymerization reactions in several classes of organic compounds; these polymerizations sometimes proceed rapidly or even explosively. Vanadium is used as a catalyst in the production of synthetic rubber and sulfuric acid.
Hazard
Vanadium powder, dust, and most of its oxide compounds are explosive when exposedto heat and air. They are also toxic when inhaled. Vanadium chloride compounds are strongirritants to the skin and poisonous when ingested.
Many of its compounds must be stored in a dry, oxygen-free atmosphere or in containersof inert gas. Protective clothing and goggles should be worn when handling vanadium, as wellas with most of the other transition elements.
Health Hazard
Exposures to high levels of vanadium cause harmful health effects. The major effects from breathing high levels of vanadium are on the lungs, throat, and eyes. Workers who breathe vanadium for short and long periods show lung irritation, coughing, wheezing, chest pain, runny nose, and sore throat. Prolonged period of exposures to respirable dusts and vanadium fume have caused potential symptoms of toxicity among occupational workers. The symptoms of poisoning include, but are not limited to, irritation of the eyes and throat, green tongue, metallic taste, sore throat, cough, drowsiness, wheezing, bronchitis, abdominal cramps, nausea, vomiting, diarrhea, respiratory distress, pulmonary edema, bronchial damage, epistaxis (bloody nose), eczema, conjunctivitis, headache, dry mouth, dizziness, nervousness, insomnia, and tremor. It is not classifi able as a human carcinogen. Vanadium is a natural component of fuel oil, and workers have developed vanadium poisoning during cleaning operations on oil-fi red furnaces.
Agricultural Uses
Vanadium (V) is a silvery-white, metallic, transition
element of Group 5 of the Periodic Table and
exhibits a range of valencies from +2 to +5. The ores
containing vanadium include vanadite and carnotite.
The pure metal, formed by the reduction of vanadium
oxide with calcium, is generally used as an alloying
element for steel and iron. Several vanadium compounds
are used as oxidation catalysts. They are also used as
coloring agents in the ceramic industry.
Vanadium comes under the category of beneficial
elements which are non-essential but beneficial to plant
growth. It is a very useful nutrient for the green alga Scenedesmus, but the exact amount of vanadium needed
for the growth of higher plants is yet to be established.
Vanadium may replace molybdenum to some extent
in nitrogen fixation by micro-organisms such as
Azotobacter and Rhizobium. An increase in growth due to
vanadium is seen in asparagus, rice, lettuce, barley and
corn. It has also been speculated that vanadium may
function in biological oxidation-reduction reactions.
Vanadium stimulates growth and nitrogenase activity
in Anabaena variabilis in the absence of molybdenum.
Low concentrations of vanadium are beneficial for the
optimal growth of micro-organisms and higher plants.
Generally, the concentration of vanadium in plants is
about 1 ppm.
Industrial uses
Vanadium is a member of the d-block metals and belongs to group 5 of the periodic table of elements. Vanadium can be found in the earth s crust in numerous minerals and is isolated from ores mostly as a by-product. Its main application is in the steel industry, where it is used as an alloy in combination with iron. Vanadium pentaoxide is also being used as a catalyst for the production of sulfuric acid. The metal vanadium has very similar properties to titanium. Therefore, it is not surprising that its metallocene, vanadium dichloride, was also subjected to research as a potential anticancer agent. Vanadium is an essential trace metal in the human body, but still very little is known about its biological function. Vanadium is mainly found in its ionic state bound to proteins.
Safety Profile
An inhalation hazard. Poison by subcutaneous route. Questionable carcinogen with experimental tumorigenic data. Flammable in dust form from heat, flame, or sparks. Violent reaction with BrF3, Cl2, lithium, nitryl fluoride, oxidants. When heated to decomposition it emits toxic fumes of VOx. See also VANADIUM COMPOUNDS.
Potential Exposure
Vanadium is used as a catalyst in the production of synthetic rubber and sulfuric acid. Most of the vanadium produced is used in ferrovanadium and of this the majority is used in high speed and other alloy steels with only small amounts in tool or structural steels. It is usually combined with chromium, nickel, manganese, boron, and tungsten in steel alloys.
Carcinogenicity
The results of 2-year NTP inhalation study on F344/N rats (at concentrations of 0, 5, 1, or 2mg/m3) and B6C3F1 mice (at concentrations of 1, 2, or 4mg/m3)exposedfor6hperdayfor5daysperweekindicate clear evidence of carcinogenic activity of vanadium pentoxide based on the occurrence of alveolar/bronchiolar neoplasms. Exposure to V2O5 caused a spectrum of nonneoplastic lesions in the respiratory tract (nose, larynx, and lung), including alveolar and bronchiolar epithelium hyperplasia, in?ammation, ?brosis, and alveolar histiocytosis of the lung in male and female rats and mice, and an unusual squamous metaplasia of the lung in male and female rats. Hyperplasiaofthebronchiallymphnodesoccurredinfemale mice. In a 16-day inhalation study in rat, alveolar and bronchiolar epithelial hyperplasia was observed in most rats exposed to 2 or 4mg/m3 V2O5 on days 6 and 13.
Environmental Fate
Vanadium is a gray metal with a body-centered cubic crystal system. Vanadium has oxidation states of +2, +3, +4, and +5. Vanadium is released naturally into the atmosphere by the formation of continental dust, marine aerosols, and volcanic emissions. Vanadium cannot be destroyed in the environment, but it can transform or change its form and attach or separate from airborne particulate, soil, water particulate, and sediment. Vanadium particles in the air settle to the ground or are washed out of the air by rain. Smaller particles, such as those emitted from oil-fueled power plants, may stay in the air for longer times and are more likely to be transported farther away from the site of release. The transport and partitioning of vanadium in water and soil is influenced by many factors, including acidity of the water or soil and the presence of particulates. Vanadium can either be dissolved in water as dissolved ions or may become adsorbed to particulate matter. As an element, vanadium cannot be degraded but can undergo various precipitation or ligand exchange reactions. Bioconcentration is insignificant.
