METHOD FOR PRODUCING ALKALI ALUMINOSILICATE GLASS

摘要

The present invention relates to a method for producing alkali aluminosilicate glass having an Al2O3 content of more than 1% by mole by melting a glass starting material that contains silica sand, an aluminum compound-containing starting material and an alkali metal oxide-containing starting material. In this method for producing alkali aluminosilicate glass, the ratio of the specific surface area of the aluminum compound-containing starting material (SW(Al)) to the specific surface area of the silica sand (SW(Si)), namely SW(Al)/SW(Si) is 6.0 or less.
