氟钙云母系玻璃陶瓷(Al_2O_3-CaO-F-K_2O-Na_2O-SiO_2)的断裂韧性可以高达5.0MPa·m~(1/2),但其化学稳定性却难以满足齿科修复要求。本研究目的在于验证这样一个假说,即增加玻璃陶瓷当中Al_2O_3所占比
Fracture toughness of calcium-calcium-mica glass-ceramics can reach as high as 5.0MPa · m ~ (1/2), but its chemical stability can not meet the requirements of dental restoration. The purpose of this study is to verify the hypothesis that increasing the proportion of Al 2 O 3 in glass ceramics
