Abstract

The present invention provides a low temperature fired porcelain comprising crystalline phases including sanbornite, celsian and β-cristobalite phases when measured by a high power X-ray diffractometer. The ratio of the peak intensity of (101) plane of α-cristobalite phase to the peak intensity of (101) plane of sanbornite phase is not higher than 5%. The porcelain is of a low temperature fired porcelain of silica-alumina-barium oxide system with cristobalite phase precipitated, in which the incidence of cracks in the porcelain may be reduced.
