What is nickel oxide powder? Nickel (II) oxide, with a chemical formula of NiO and molecular weight of 74.71, is a green-black cubic crystal. It is soluble in acid and ammonia and insoluble in water. When heated, its color turns yellow. It is obtained from the reaction of nickel and oxygen at more than 400 ℃ or from the pyrolysis of nickel carbonate at 350 ℃. It makes alloys, storage cells, glass, enamel, ceramics, electronic components, nickel salts, and catalysts. Nickel oxide is an inorganic compound with a chemical formula of NiO, which is olive green crystalline powder, Insoluble in water, mainly used as a sealer and colorant for enamel, a pigment for ceramics and glass, and also used in the production of nickel-zinc ferrite in the production of magnetic materials. It can also be used as a raw material to manufacture nickel salts, a nickel catalyst, and in metallurgy and kinescope. On October 27, 2017, the list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization (WHO) was preliminarily sorted for reference, and nickel compounds were included in the list of category one carcinogens.
Handling and storage of nickel oxide powder Notes for operation: closed operation, local ventilation. Operators must receive special training and strictly abide by the operating procedures. It is recommended that operators wear dust masks, rubber gloves, and rubber gloves to avoid dust generation. When handling acids, they should be loaded and unloaded gently to prevent damage to packaging and containers and equipped with leakage emergency treatment equipment. Empty containers may contain harmful substances. Storage precautions: Store in a cool and ventilated warehouse. Keep away from kindling and heat sources. Store separately from acids and edible chemicals. Please do not mix them. The storage area should be equipped with appropriate materials to contain leakage.
Synthesis method of nickel oxide powder: 1. Nickel salt calcination decomposition method is used to remove copper, iron, manganese, chromium, and other impurities from nickel alloy scraps (including iron, copper, chromium, etc.) with hydrogen sulfide, hydrogen peroxide, sodium carbonate, ammonia, and react with sulfuric acid to produce ammonium nickel sulfate, and then calcine and crush to produce nickel oxide finished products 2. Place NiCO3 or Ni (NO3) 2 · 6H2O in a platinum crucible, heat it at 1000-1100 ℃ for six h, and then cool it in an N2 gas stream without O2.
Price of nickel oxide powder Nickel oxide powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of nickel oxide powder. A large amount of large amount will be lower. The price of nickel oxide powder can be found on our company's official website.
