A ceramic composite for light conversion comprising a solidified body in which crystalline phases of oxides are three-dimensionally entangled and a method for manufacture thereof. A manufacture method of a ceramic composite for light conversion is characterized in that a polishing step is provided in a chemical mechanical polishing (CMP) process applied to the surface of a solidified body with a structure in which an AlOphase and other phases are three-dimensionally entangled.

Ceramic composite for light conversion and method for manufacture thereof

A method for producing a ceramic composite for light conversion including first step of forming the step level difference such that an oxide crystal phase other than Al2O3 phase of a surface of a solidified body is in a convex shape relative to an Al2O3 phase by subjecting the surface of the solidified body having a structure in which the Al2O3 phase and the oxide crystal phase other than Al2O3 phase are continuously and three-dimensionally entangled with each other to dry etching, and a second step of reducing the step level difference by subjecting the solidified body subjected to the dry etching to CMP or MP.
