Abstract: Objective: Research the thermal treatment schedule of K2O-Na2O-Al2O3-SiO2 system dental glass ceramics matching Al2O3 ceramics. Methods: Select and analysis the raw material according to K2O-Na2O-Al2O3-SiO2 system ,produce glass - Al2O3 composite ceramic material. The products were analyzed by polaring microscope and X-ray diffractometer, the compressive strength was tested by material machine. Results: Leucite microcrystal was about 1.0μm, distributed in the glass matrix evenly; The compressive strength was about 460MPa, even the interface of glass combined with Al2O3 ceramics need in-depth exploration. Conclusion: K2O-Na2O-Al2O3-SiO2 system dental glass ceramics can be sintered and match Al2O3 ceramics with special thermal treatment schedule.
