Abstract
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 Al2O3 phase and other phases are three-dimensionally entangled.
