NICKEL SULFIDE Chemical Properties,Usage,Production

Chemical Properties

black powder(s); trig, yellow metallic luster; enthalpy of fusion 30.10 kJ/mol; can be formed by fusing Ni powder(s) and molten sulfur; other sulfides include Ni2S, 12137-08-5, Ni3S2, 12035-72-2 (heazlewoodite), NiS2, 12035-51-7, and Ni3S, 12137-12-1 (polydymite) [KIR81] [STR93] [CRC10] [JAN85]

Preparation

The black nickel sulphide precipitated from nickel(II) salt solutions by ammonium sulphide in neutral but not strongly acid solution is the so-called α-NiS ; it consists largely of amorphous Ni(SH,OH)2 when first precipitated. At low pH this crystallizes to give mainly the rhombohedral γ-NiS, while at higher pH the hexagonal β-NiS(Ni_1-XS) crystallizes.

Flammability and Explosibility

Non flammable

Safety Profile

Confirmed carcinogen with experimental carcinogenic and neoplastigenic data. Mutation data reported. When heated to decomposition it emits toxic fumes of SOx. See also NICKEL COMPOUNDS and SULFIDES.
