Abstract: The process of chemical synthesis of a new kind of solid lubricant and oil additive--nickel oxythiomolybdate
and one of its precursor material ammonium oxythiomolybdate were studied. Their composition, structure and morphology were investigated by chemical analysis,
X-ray diffraction, electron microprobe and SEM. The results obtained show that their optimum parameters for synthesizing are: pH=4~5, T=30℃, and pH=7~9,
T=--5~0℃. NiMoO2S2 as a solid lubricant and an oil additive from 20℃ to 600℃ has good tribological behaviors, and can be regarded as a new kind of lubricant applied in a wide temperature range.

Key words: NiMoO2S2, (NH4)2MoO2S2, additive
