Oxidation of Molten Nickel and Cobalt Sulfides

An amount of 100 mg of nickel or cobalt sulfide was put in a slender alumina tube of 3 mm ID and 25 mm length and oxidized at 1473 K in a mixed O2–Ar gas stream. Sulfur atomic fraction, xs, was 0.30 to 0.40 for nickel sulfide and 0.400 to 0.446 for cobalt sulfide. When the xs was lower, the NiO or C...
