(57) [Abstract] [Purpose] An object of the present invention is to provide a powdered sulfurized oxymolybdenum dithiocarbamic acid which is excellent in friction and wear characteristics when used as a grease composition, exhibits excellent lubricity effectively, and is less corrosive. It is intended to provide a composition, a method for producing the composition, and a grease composition containing the composition. The powdery sulfurized oxymolybdenum dithiocarbamic acid composition of the present invention has the general formula (1): (R 1 , R 2 , R 3 and R 4 are hydrocarbon groups and may be the same or different, and the total carbon number of R 1 to R 4 is 4 to 36. Further, X is sulfur or oxygen, and the total composition of all X is represented by S m O n , and 1.7 ≦ m ≦ 3.5 and 0.5 ≦ n ≦ 2.3. ), And the constituent particles have a particle size of 50 μm or less. |
