| titleOfInvention | Method for manufacturing silicon nitride ceramics sintered body |
| abstract | (57) [Summary] (Corrected) [Purpose] The sintering reaction is promoted and the heterogeneous grains are promoted by uniformly dispersing the auxiliary components necessary for manufacturing the silicon nitride ceramics sintered body. Provided is a method for producing a silicon nitride ceramics capable of reducing the additive amount necessary for obtaining desired strength and toughness by eliminating growth. [Constitution] In an organic solvent in which silicon nitride powder is dispersed, Yttrium, cerium, magnesium, hafnium, Two or more kinds selected from alkoxides of zirconium, silicon and aluminum are added, and they are partially hydrolyzed with water of 1 mol times or more and 4 mol times or less with respect to the total amount of the above alkoxides, and are sealed from air A method for producing a silicon nitride ceramics sintered body, which comprises coating the silicon nitride powder with an oxide of the above metal by aging, and then molding and firing the powder obtained by separating and drying. . |
