Ceramic composites

摘要

Problem to be solved: to provide a ceramic composite material capable of improving the wavelength conversion efficiency by uniformly scattering primary light and wavelength converted secondary light.Solution: at least two oxide phases of the Y3Al5O12 phase and the Al 2O 3 phase are contained in the lamellar structure, and MgO is contained at least 10 ppm or more and 500 ppm or less, and the lamellar structure has the interface of the Y3Al5O12 phase and the Al 2O 3 phase 30 / mm or more Ceramic composites containing at 0 / mm or less.Selection diagram
