Neodymium oxide Chemical Properties,Uses,Production

Chemical Properties

Neodymium Oxide, Nd2O3 is a blue-grey powder that is composed of the rare earth neodymium and oxygen. hygroscopic; absorbs atmospheric CO2; hexagonal; has slightly red fluorescence. Water insoluble, soluble in acids. It has special properties that make it very useful to the glass and ceramics industries. Neodymium Oxide gives a good aqua color in most glaze bases at 1-2%. At 4-7% it gives a pleasant lavender/grape color that appears as a different color under different artificial light sources. It is very strongly affected by iron, particularly in oxidation, giving a reliable perfect neutral transparent gray. Avoid trace iron impurities to achieve the brightest blue and lavender colors.
Neodymium Oxide

Physical properties

Blue powder; hexagonal crystals; fluoresces red; density 7.24 g/cm3; melts around 1,900°C; practically insoluble in water, 30 mg/L at 75°C; dissolves in acids.

Uses

Neodymium oxide (Nd2O3) is a light-blue powder used to color glass and as a pigment for ceramics. It is also used to make color TV tubes.

Production Methods

Neodymium oxide is produced from the two principal rare earth minerals, monazite, and bastnasite. The oxide is obtained as an intermediate in the recovery of neodymium metal (See Neodymium).
The oxide also may be formed by thermal dissociation of neodymium oxalate, hydroxide or carbonate:
Nd2(C2O4)3 → Nd2O3 + 6CO2
2Nd(OH)3 → Nd2O3 + 3H2O
Nd2(CO3)3 → Nd2O3 + 3CO2.

Reactions

The anhydrous oxide absorbs moisture from the air at ambient temperatures forming hydrated oxide. The oxide also absorbs carbon dioxide from air, forming neodymium carbonate.
Neodymium oxide dissolves in strong mineral acids forming corresponding neodymium salts:
Nd2O3 + 3H2SO4 → Nd2(SO4)3 + 3H2O
Reactions with acetic and other organic acids produce corresponding salts. When heated with ammonium chloride at 300 to 400°C, the oxide converts to chloride liberating ammonia and water:
Nd2O3 + 6NH4Cl → 2NdCl3 + 6NH3 + 3H2O
When heated with hydrogen fluoride, the product is neodymium fluoride:
Nd2O3 + 6HF → 2NdF3 + 3H2O
The oxide is reduced to neodymium metal when heated with hydrogen, carbon monoxide, or other reducing agents.

Safety Profile

Low toxicity by ingestion.

Toxicology

Neodymium oxide is belong to a rare earth metal. These metals are moderately to highly toxic. The symptoms of toxicity of the rare earth elements include writhing, ataxia, labored respiration, walking on toes with arched back and sedation.

Purification Methods

Dissolve it in HClO4, precipitate it as the oxalate with doubly recrystallised oxalic acid, wash it free of soluble impurities, dry it at room temperature and ignite it in a platinum crucible at higher than 850o in a stream of oxygen. It is a blue powder. [Tobias & Garrett J Am Chem Soc 80 3532 1958.]
