ALKALI ALUMINOSILICATE GLASS FOR 3D PRECISION MOLDING AND THERMAL BENDING
摘要：
An alkali aluminosilicate glass for 3D precision molding and thermal bending is provided. The glass has a working point lower than 1200° C. (104 dPas) and a transition temperature Tg lower than 610° C. The glass has, based on a sum of all the components in percentage by weight, 51-63% of Si02; 5-18% of Al203; 8-16% of Na20; 0-6% of K20; 3.5-10% of MgO; 0-5% of B203; 0-4.5% of Li20; 0-5% of ZnO; 0-8% of CaO; 0.1-2.5% of Zr02; 0.01-
