PRODUCTION PROCESS FOR OXIDE CERAMIC, TRANSLUCENT SPINEL CERAMIC STRUCTURE, AND OPTICAL DEVICE FOR COLOR CRYSTAL LIQUID PROJECTOR

摘要

PROBLEM TO BE SOLVED: To provide a production process for an oxide ceramic which is capable of forming a high quality sintered body (oxide ceramic) having few defects such as pores inside with a simple process.;SOLUTION: The production process for an oxide ceramic relates to a production process for an oxide ceramic including at least one kind of metal elements selected from the group consisting of Mg, Zn, and Al. The production process comprises a step to form a fine particle-deposited body 19 by depositing a deposited layer of the fine oxide particles of the metal element on the surface of a core member 18 using vapor phase synthesis, and a step to heat the fine particle-deposited body 19. Preferably, the oxide ceramic is a spinel (translucent spinel ceramic 20). More preferably, the production process has a step to densify the fine particle-deposited body 19 after the heating step.;COPYRIGHT: (C)2011,JPO&INPIT
