The present invention relates to glass manufacturing area, discloses alumina silicate glass and its preparation method and application.On the basis of the integral molar quantity of the alumina silicate glass, in terms of oxide, the alumina silicate glass contains：SiO 2 ：62~68%, Al 2 O 3 ：11~15%, B 2 O 3 ：0~4%, MgO：5~15%, CaO：1~10%, SrO：3~9%, ZnO：0.01~1%, MoO 3 ：0.001~0.5%.The alumina silicate glass prepared using the method for the present invention is green, with good heat endurance, higher annealing point temperature and relatively low fusion temperature and forming temperature can be had concurrently, glass still has higher mechanical strength after being thinned, moreover, the resistance to chemical corrosion of the alumina silicate glass is excellent. |
