摘要：PROBLEM TO BE SOLVED: To obtain an oxide sintered compact of fluorite type or its derivative structure whose interface is clean without purifying raw material powder and to provided a method for producing the sintered compact. SOLUTION: In a method for producing an oxide sintered compact having a crystal structure of fluorite type or its derivative structure, when the oxide powder of a raw material is formed, an active oxide colloid of Si or Al is uniformly added in a wet state to the powder or is uniformly mixed after the formation of the powder. Consequently impurities of Si or Al in the sintered compact are collected as a precipitate to produce an oxide sintered compact having a crystal structure of fluorite type or its derivative structure with an interface from which the impurities are removed.
