- •
CaO, TiO2, ZrSiO4 (CTZ) as nucleating agents were added to barium borosilicate glass.
- •
The samples with 45–55 wt% CTZ possess CaZrTi2O7-2M and CaTiSiO5 crystalline phases.
- •
CTZ-45 (45wt% CTZ) possesses only CaZrTi2O7-2M phase after annealing at 680–740 °C.
- •
CTZ-45 possesses CaZrTi2O7-2M and CaTiSiO5 phases after annealing at 900–1050 °C.
- •
CTZ-45 annealing at 950 °C shows the lower leaching rates of B, Na and Nd than CTZ-0 and CTZ-55.
