Is nickel oxide a harmful substance?
What is Nickel oxide powder?
Nickel oxide is a kind of green to black-green cubic crystal powder, which turns yellow when overheated. The relative density is 6.67. The melting point is 1984℃. Soluble in acid and ammonia, insoluble in water and liquid ammonia. When heated to 400℃, it becomes Ni2O3 by absorbing oxygen in the air. At 600℃, it was reduced to nickel monoxide. The nickel monoxide prepared at low temperature has chemical activity, and the nickel monoxide calcined at 1000℃ is green and yellow with low activity. Moreover, with the increase of preparation temperature, its density and resistance increase while its solubility and catalytic activity decrease.
Main applications of Nickel oxide powder
1. Used as adhesive and colourant for enamel and pigment for ceramics and glass. In the production of magnetic materials, it is used to produce nickel-zinc ferrite, etc., as well as to make nickel salt raw material, nickel catalyst and apply in metallurgy and kinescope. Used as electronic component material, catalyst, enamel coating and storage battery material.
2. NiO can be used to prepare simple nickel by reduction, but it should be noted that NiO can never be reduced by CO under unprotected conditions. This is because Ni and CO react to form highly toxic and volatile nickel tetracarbonyl Ni(CO)4, which is difficult to detoxify and prone to danger. Usually, safer reducing agents such as H2 are used for reduction.
3. Used for making nickel salts, ceramics, glass, catalysts, magnetic materials, etc.
4. Used as electronic component material and storage battery material.
Safety characteristics of nickel oxide
Nickel oxide powder is packed in iron drums lined with polyethene plastic bags with net weights of 30kg, 40kg and 50kg. Store in a ventilated and dry warehouse. Containers must be sealed to prevent moisture and caking. It can't be stored and transported together with strong acids and alkalis. In case of fire, water can be used to put out the fire. And toxicity protection: it can enter cells, causing the destruction of enzymes and metabolic processes in cells, and may cause carcinogenesis due to the formation of some carcinogens. Contact with nickel salt can cause nickel eczema and nickel scabies. Maximum allowable concentration in the air: bivalent nickel oxide is 0. 5mg/m3 (calculated as nickel). Production operators should wear gas masks and gas masks to prevent direct skin contact to the greatest extent. Try to implement mechanized operations to avoid dust. People exposed to nickel compounds at work should have a regular physical examination.
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.
