Nickel Sulfide - Nickel Leucahydrate

Japanese: 硫化ニッケル - リュウカニッケル
Nickel Sulfide - Nickel Leucahydrate
A general term for compounds of nickel and sulfur.
[Trnickel disulfide]
Chemical formula: Ni 3 S 2. It is obtained by heating fine nickel powder to 190-280°C in a hydrogen sulfide stream. There are two modifications: high-temperature (orthorhombic) and low-temperature.
[Hexanedickel hexasulfide]
Chemical formula: Ni 7 S 6 . It is obtained by vacuum sealing sponge nickel and sulfur in a quartz tube and then heating it for a long time at 500°C. There are two modifications: high-temperature (α) and low-temperature (β). The α form is an orthorhombic crystal system and is stable at 400-573°C.
[Nickel(II) sulfide]
Chemical formula: NiS.
