• 製造方法

  Pure NiO is reduced with pure H2 at 275-285℃ until constant weight. The fine Ni powder is heated at once with pure CO (completely free of O3) for 260 hours at 270℃. The Ni3C thus produced is pyrophoric. This may be remedied by heating for a long time in O2-free nitrogen at 250℃ and cooling in the N2 stream.
