(57) [Summary] [PROBLEMS] To provide a method for producing solid lubricant particles, which has no problem in terms of properties and heat resistance and which can be sintered with a base material to obtain a high-strength self-lubricating composite material. According to the method for producing solid lubricant particles according to the present invention, the solid lubricant particles include a silicon-based liquid (substance A) of water glass or colloidal silica suspension, mica, talc, aluminum silicate, and alumina cement. A step of uniformly mixing reaction products of one or more frits (substance B) selected from the group as a binder to perform a granulation treatment, and to enhance the strength of the granule obtained in the step To 150 ~ And a heat treatment step at 1000 ° C. |
