CERAMIC COMPOSITE FOR PHOTOCONVERSION, AND METHOD FOR MANUFACTURE THEREOF

摘要

Disclosed are a ceramic composite for light conversion with a flat surface obtained even in a solidified body in which the plurality of crystalline phases of oxides is continuously and three-dimensionally entangled with each other 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 CMP process applied for the surface of a solidified body with a structure in which an Al 2 O 3 phase and a crystalline phase of oxides other than Al 2 O 3 are continuously and three-dimensionally entangled with each other, and pH of a polishing liquid is adjusted between 11 and 12 when performing the CMP process. A ceramic composite for light conversion includes a solidified body with a structure, in which an Al 2 O 3 phase and a crystalline phase of oxides other than Al 2 O 3 are continuously and three-dimensionally entangled with each other and the step level difference between Al 2 O 3 phase and a crystalline phase of oxides other than Al 2 O 3 on the surface of the solidified body is equal to 0.010 µm or less.
