Since anatase is metastable phase we could observe no clear diffraction pattern of anatase in the Bi-containing CaBBAT glass-ceramics with various heat-treatment conditions. Therefore we can conclude that the addition of ZnO improves the transparency of the TiO2 glass-ceramics and affects the crystallization of metastable phase.
