Title:
PRODUCTION OF CERAMIC SINTERED BODY
Document Type and Number:
Japanese Patent JPH01126276
Kind Code:
A
Abstract:
PURPOSE:To facilitate production by mixing an alkoxide compd. of a metal in the form of a nonaqueous soln. with ceramic powder to uniformly stick the compd. of the metal to the surface of the ceramic powder, then sintering the mixture. CONSTITUTION:The alkoxide compd. of the metal such as yttrium is mixed in the form of the nonaqueous soln. of alcohol, etc., uniformly with the ceramic powder. The moisture contained at a small ratio in the nonaqueous soln. and the moisture or OH groups on the surface of the ceramic powder and the alkoxide of the metal react with each other and the yttrium oxide sticks easily and uniformly to the surface of the ceramic powder at this time. This ceramic powder is then sintered to form the ceramic sintered body. The addition of the assistants is executed in a short period of time without subjecting the powder to a mechanical mixing treatment with a ball mill, etc., and, therefore, the production of the ceramic sintered body is facilitated.
