  • Alumina ceramic
    Patent number: 8198204
    Abstract: An alumina ceramic contains a Ba0.808Al1.71Si2.29O8 phase. The alumina ceramic has high reflectivity and is useful as a reflecting material for a light emitting element. The alumina ceramic which exhibits an X-ray diffraction pattern having a ratio of the peak intensity at 2?=43.3° to that at 22.5° of 0.5 to 2.5 has particularly high reflectivity. The alumina ceramic shows high reflectivity particularly at wavelengths ranging from 300 to 400 nm.
