Production of ceramics sintered body
专利汇可以提供Production of ceramics sintered body专利检索，专利查询，专利分析的服务。并且PURPOSE: To obtain a titled sintered body without generating destruction by mixing a specific thermoplastic resin as a binder with ceramics powder and sintering the mixture after molding and degreasing so that the uniform molding prior to the degreasing is degreased at a low temp.
CONSTITUTION: (a) 100pts.wt. polyα-methyl styrene or several thousandsWseveral millions mol.wt. such as home polymer of α-methyl styrene or copolymer contg. severalWseveral tens % styrene (deriv.), (meth)acrylate, etc., is dissolved together with (b) 0.01W10pts.wt. unsatd. carboxylic acid such as (meth)acrylic acid in a solvent and the soln. is subjected to a heating treatment for 30minWseveral hours at 100W200°C under (non)presence of a radial initiator to obtain the thermoplastic resin (B) which is the heat-treated polyα-methyl styrene. About 5W50pts.wt. component B as a binder is added to (A) 100pts.wt. ceramics powder such as fine Al
2 O
3 particle and (C) a plasticizer, etc., are compounded therewith at need and the mixture is molded to a desired shape. The molding is degreased at, for example, about 400°C and is then sintered at about 1,400°C.
