Manufacturing method of ceramic composite

摘要

Problem to be solved: to provide a method of manufacturing a ceramic composite capable of controlling the size of a lamella structure uniformly scattered by primary light and wavelength converted secondary light.Solution: while having a slitA plurality of die 9 in which each longitudinal direction is arranged in parallel is housed in a crucibleAluminum oxide at crucibleYttrium oxideMagnesium oxideProcess of adding raw material containing cerium oxide andHeat the crucibleThe melt 21 is prepared by melting the raw material in the crucible andThe step of forming the melt reservoir 22 in which the melt is accumulated in the upper portion of the slit through the slit andThe seed crystal 17 is brought into contact with the melt reservoir.A method of manufacturing the ceramic composite 2 having a pulling step for pulling up the seed crystal at a pulling rate of 0.9 mm / hour or more and not more than 400 mm / hour.Diagram
