Abstract: Non-oxide ceramics have a wide application in many fields, such as metallurgy, chemical engineering, mechanical engineering and electronics, due to their excellent properties. A lot of efforts have been made to synthesize sinerable ultrafine powders of non-oxide ceramics. In this paper, the progress of preparing ultrafine powders of non-oxide ceramics was reviewed. It involves mechanical grinding, reaction of elemental metal, carbothermal reduction (nitridation) of metal oxide, py-rolysis of polymer, chemical vapour deposition, and solvothermal synthesis. In particularly, the progress of carbothermal reduction (nitridation) was detailedly described.

Key words: non-oxide ceramics, ultrafine powders, synthesis, progress
