Ceramic granules, process for preparing the same, and process for producing sintered product of silicon nitride |
摘要 |
Ceramic granules for producing sintered products of silicon nitride that can be favorably used as structural materials for various heat engines such as automotive parts, gas turbines and the like, and as abrasion resistant materials and corrosion resistant materials. A process for preparing the ceramic granules and a process for preparing sintered products of silicon nitride by using the ceramic granules. Ceramic granules comprise a mixture of a silicon nitride powder, a silicon powder and an assistant, as well as an organic binder, said ceramic granules having an average particle diameter of from 50 to 300 mu m and a relative density of from 18 to 30%.
