represents crystal uniform, not soluble powder in water, depending on a way of receiving and heat treatment has color from light-to a dark zelyonnogo or black. Is inorganic binary compound of bivalent nickel with oxygen, has weak-basic properties. It is dissolved in acids. It is restored by hydrogen when heating. It is thermally very steady.
Meets in the nature in the form of rare mineral of a bunzenit.
Has two crystal modifications: α-NIO (trigonal singoniya) and β-NIO (cubic singoniya).
Density: α-NIO - 6,67 g/cm ³, β-NIO - 7,45 g/cm ³. Temperature of melting is 1682 °C, temperature of decomposition is 1230 °C.
Chemical formula: NiO.
Production of oxide of nickel is based on mine melting of the oxidized nickel ore with preliminary drying of ore from 23-27% of moisture content to 14-15%. Also it is received calcinating of nitrate, a carbonate, sulfate of nickel (II) or oxides Ni2O3, Ni3O4, NiO2.
The main use of oxide of nickel - an intermediate product when receiving salts of nickel (II), nickel-containing catalysts and ferrite.
It is applied in combinations with oxides of other metals (lithium, magnesium, manganese, the titan, etc.) in production of the semiconductors having very high temperature coefficients of resistance.
It is used by production of the enameled products as a green pigment for glass, glazes and ceramics.
Dust of protoxide of nickel possesses cancerogenic action, exerts impact on blood formation, carbohydrate exchange; class of danger 1; threshold limit value in air of a working zone of production rooms (in terms of nickel) 0,05 mg/m ³.
Nickel oxide is not liable to neutralization and destruction. The waking-up product after dry and subsequent damp cleaning is utilized in technological processes of production of nickel.
Nickel protoxide under normal conditions not of a goryuch, is fire and explosion-proof, in the air environment and sewage in the presence of other substances does not form toxic connections.
Working with protoxide of nickel have to be provided with individual protection equipment. The filtering antiaerosol respirators of the 2nd and 1st degree of protection have to be applied to protection of respiratory organs depending on concentration.
Production and laboratory rooms in which works with nickel protoxide are carried out have to be equipped with a supply and exhaust ventilation.
Packing, transportation and storage.
Oxide of nickel is packed into three-five-layer paper bags which then put in plastic bags or lno-dzhuto-kenafnye with a basis from viscose threads, and then placed in specialized containers. It is allowed to place bags in metal barrels or wooden barrels with a capacity of 50 dm ³, or steelpans with a capacity of 25 dm ³ at party less than 3 t. Plastic bags solder, and paper lno-dzhuto-kenafnye bags sew up. Mass gross of a bag should not exceed 50 kg.
Oxide of nickel is transported transport of all types according to the rules of transportations (dangerous) freights existing on transport of this look. The product packed into specialized containers is transported by rail on the open rolling stock.
Protoxide of nickel has to be stored in a packed form warehouse of the manufacturer, the consumer in the dry enclosed space.
