NiO
PROPERTY:green powder,slowly becomes yellow when heated.dissloved inacid and ammonia,not dessolved in water,when heated to 400 centigrade itcan absorb oxygen and turn into Ni2O3.when heated to 600 bentigrade itcan be reverted to NiO.
Nickel oxide.
Nickel oxide is a stable oxide and a common inorganic compound. At room temperature as green or black green powder, insoluble in water, after heating yellow.Nickel oxide is also an insulator. The preparation temperature is different, its physical properties are also different. The nickel oxide prepared at low temperature has chemical activity, while the chemical activity prepared at high temperature 1000℃ is very small, and the color is greenish-yellow.
Nickel oxide Ni2O3 is a gray-black, odorless, glossy lump that has been broken into a fine powder. Honor hot hydrochloric acid and release chlorine gas. Soluble in sulfuric acid and nitric acid and emit oxygen. Store in a ventilated, dry warehouse. The container should be sealed, moisture-proof and heat-proof. Slightly hazardous to whom. Do not allow undiluted or large quantities of product to contact ground water, water courses or sewage systems. Do not release material into the environment without government permits.
