Research on Processing Conditions of CBS Transparent Glass-Ceramics
Abstract:
On the basis of experimental verification, the optimum processing conditions of CaO-B2O3-SiO2 (CBS) system transparent glass-ceramics were obtained. Composition of main raw powders (wt%) was:CaO 38%,SiO2 40%,B2O3 12%.The precursor glass was prepared by melting method and annealed at 560°C for 2h and cooled to room temperature at a speed of 5°C/min.The best nucleating agent is P2O5. The appropriate heat treatment regime to precursor glass was determined to be 2h at 600°C for nucleation and 3h at 780°C for crystallizition.Under this condition,the transmittion of glass-ceramics at the range of visable light is 72% in average and Sm3+ keep good luminescence property doped in this host material.
