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

The present disclosure relates to glass manufacturing, a glass composition, glass with a low inclusion content and a preparation method therefor and use thereof. The composition comprises 50-64 wt. % SiO, 14-24 wt. % AlO, 0-7 wt. % BO+PO, 0.5-7 wt. % MgO, 1-10 wt. % CaO, 0-9 wt. % SrO, 0.1-14 wt. % BaO, 0.1-5 wt. % ZnO, 0.1-4 wt. % TiO, 0.1-7 wt. % YO+LaO+NdO, and &#x3c;0.05 wt. % RO, wherein RO is a sum of the content of LiO, NaO and KO, and the composition satisfies the following conditions: (1) a temperature Tcorresponding to a viscosity of 100 P is 1730&#xb0; C. or higher; (2) a surface tension at 1300&#xb0; C. is less than 420 mN/m. The glass prepared by the glass composition and the glass with a low inclusion content preparation method has the advantages of having low inclusion content, having a simple preparation process, being low in cost and so on.
