摘要:
Exemplary embodiments of the present invention provide lithium disilicate crystalline glass containing cristobalite crystal phase for high strength and aesthetic traits and its manufacturing process thereof. More specifically, exemplary embodiments of the present invention provide the high strength and aesthetic lithium disilicate crystalline glass, one kind of dental restoration materials, and its manufacturing method which induces the growth of the different crystal phase, cristobalite, from glass with lithium disilicate crystal. Exemplary embodiments of the present invention propose a lithium disilicate crystalline glass containing cristobalite crystal phase in glass matrix in the system of 11 - 13 wt% Li 2 O, 70.0 - 77.0 wt% SiO 2 , 2 - 3wt% P 2 O 5 working as nuclear formation agent, 2 - 5 wt% Al 2 O 3 to increase glass transition temperature and softening temperature, as well as chemical durability of the glass, 2.0- 3.0 wt% ZrO 2 , 1 - 4 wt% colorants, not including MgO, ZnO, F, and La 2 O 3 , because they reduce light transmittance.
