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. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
ニッケルと硫黄の化合物の総称。 [二硫化三ニッケル] 化学式Ni3S2。ニッケルの微細粉末を硫化水素気流中で190~280℃に加熱すると得られる。高温型(斜方晶系)と低温型の2変態がある。 [六硫化七ニッケル] 化学式Ni7S6。海綿状ニッケルと硫黄とを石英管中に真空封入後500℃で長時間加熱すると得られる。高温型(α)と低温型(β)の2変態がある。α形は斜方晶系で400~573℃で安定。 [硫化ニッケル(II)] 化学式NiS。 出典 株式会社平凡社世界大百科事典 第2版について 情報 |
