Abstract
Glass ceramics for dental crown prosthesis were prepared by crystallization of CaO-MgO-SiO2-P2O5-TiO2 glasses. Their crystallization behaviors have been investigated as a function of heattreatment temperature and holding time in relation to mechanical properties. The results are as follows: Vickers hardness and bending strength of glass ceramics increased due to the precipitation of apatite, whitlockite,
