摘要： A luminous glass ceramic comprising, in percent by weight, the following components: SiO2 50-65 (%) P2O5 0-10 Al2O3 18-30 Li2O 2-6 MgO 0.2-6 ZnO 0-2 CaO 0-4 BaO 0.5-6 TiO2 1-4 ZrO2 1-4 As2O3 + Sb2O3 0-2 wherein a total amount of SiO2 and P2O5 is 50-70 wt. %, a ratio of P2O5 to SiO2 is 0-0.18, a ratio of Al2O3 to SiO2 is 0.30-0.55, one or more rare earth elements are added to the glass ceramic on an oxide basis of 0.1-30 wt. % to an total amount of other components, Na2O component, K2O component, and PbO component are not essentially contained, and the glass ceramic has a thermal shock resistance |&Dgr;t|° C. of not less than 150, which is obtained by following equation, |&Dgr;t|=[flexural strength]×(1−[Poisson's ratio])/([coefficient of thermal expansion]×[Young's modulus]).
