Abstract:
The invention relates to the field of glass manufacturing, and discloses non-alkali aluminum silicate glass and a preparation method as well as application thereof. A glass melt of the non-alkali aluminum silicate glass at 1600° C. has a resistivity of 200 Ω·cm or less; a temperature T35000 corresponding to 35000 P viscosity is 1250° C. or more; an annealing point corresponding to 1013 P viscosity is 790° C. or more, based on a total molar weight of the non-alkali aluminum silicate glass, the non-alkali aluminum silicate glass comprises, by oxide, 69-73 mol % of SiO2, 11-15 mol % of Al2O3, 0-2 mol % of B2O3, 2-8 mol % of MgO, 2-8 mol % of CaO, 0-3 mol % of SrO, 3-10 mol % of BaO, 0.1-2 mol % of ZnO, 0.02-0.7 mol % of RE2O3, 0.01-0.5 mol % of Se2O3 and R2O, less than 0.05 mol %, wherein RE represents rare earth elements, and R represents alkali metals.
