Standrad：ASTM B127-1998; ASTM B162-1999
Material：Nickel 201 - UNS N02201 - Ni201 - Pure Nickel; N4,N5,N6,N7, N02200, N02201, NCu28-2.5-1.5, NCu40-2-1, NCu30, Monel400, NO6600
Several preparation methods of metal nickel are briefly described:
☆Electrolysis method ☆ Carbonylation method ☆ Hydrogen reduction method
① Electrolysis. The enriched sulfide ore is calcined into oxide, reduced to crude nickel by carbon, and then pure metal nickel is obtained by electrolysis.
② Carbonylation method. Nickel sulfide ore and carbon monoxide reaction to produce tetracarbonyl nickel, heated decomposition, and high purity metal nickel.
③ Hydrogen reduction method. Nickel metal can be obtained by reducing nickel oxide with hydrogen.
