    摘要: Exemplary embodiments of the present disclosure provide a lithium silicate crystalline or amorphous glass overlaying the top surfaces of zirconia and the manufacturing process thereof. More specifically, exemplary embodiments of the present disclosure provide a lithium silicate glass or lithium silicate crystalline glass with high light transmittance and good coloring characteristics and the manufacturing process thereof, which overlays the top surface of zirconia with high mechanical strength, frameworks, or copings.The lithium silicate crystalline or amorphous glass may include 10-15 wt % Li2O, 71.1-85.0 wt % SiO2, 2-5 wt % P2O5 working as nuclear formation agent, 1-5 wt % Al2O3 to increase glass transition temperature and softening temperature, as well as chemical durability of the glass, and 0.01-1.0 wt % ZrO2 which increases the binding strength of the zirconia substructure.
