Process for the production of a conductive silicon nitride composite sintered body |
摘要 |
A conductive silicon nitride composite sintered body having an average grain size of 200 nm or less and whose relative roughness (Ra) after electric discharge machining is 0.6 mu m or less can be obtained by grinding/mixing a silicon nitride powder and a metal powder together until the average particle size of the silicon nitride powder becomes 30 to 60 nm, and subsequently by molding and sintering. With the contexture that is characteristic of the present invention, it is possible to obtain a conductive silicon nitride composite sintered body having electric conductive particles of 5 to 60 volume percent that is capable of electric discharge machining. <IMAGE>
