The present invention discloses an aluminosilicate glass composition, aluminosilicate glass and a preparation method therefor and application thereof. Based on the total molar weight of the aluminosilicate glass composition, the aluminosilicate glass composition comprises, by oxide, 67-74 mol % of SiO, 10-15 mol % of AlO, 0-5 mol % of BO, 1-10 mol % of MgO, 1-10 mol % of CaO, 0-3 mol % of SrO, 2-8 mol % of BaO, 0.1-4 mol % of ZnO, 0.1-4 mol % of REOand less than 0.05 mol % of RO, wherein RE represents rare earth elements, and R represents alkali metals.

Aluminosilicate glass composition, aluminosilicate glass, preparation method therefor and application thereof

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&#xb0; C. has a resistivity of 200 &#x3a9;&#xb7;cm or less; a temperature Tcorresponding to 35000 P viscosity is 1250&#xb0; C. or more; an annealing point corresponding to 1013 P viscosity is 790&#xb0; 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 SiO, 11-15 mol % of AlO, 0-2 mol % of BO, 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 REO, 0.01-0.5 mol % of SeOand RO, less than 0.05 mol %, wherein RE represents rare earth elements, and R represents alkali metals.

Non-alkali aluminum silicate glass, preparation method therefor and application thereof

A composition for glass, alkaline earth aluminosilicate glass, and a preparation method therefor and applications thereof. Based on the total number of moles of each component and the counting of oxides, the composition contains 68-73 mol % of SiO, 11.5-15 mol % of AlO, 2-6 mol % of MgO, 2.5-7.5 mol % of CaO, 0-3 mol % of SrO, 2-7 mol % of BaO, 0-4 mol % of ZnO and 0.05-1.5 mol % of TiO. The glass has a high strain point, a high Young's modulus, a high specific modulus, a high Vickers hardness, high chemical stability, a high refractive index and high glass formation stability, and has a lower forming temperature, a lower melting temperature, a lower thermal expansion coefficient, a lower surface tension, a lower density, and low glass manufacturing difficulty.
