Abstract
Aluminosilicate glasses whose composition is free of alkali metals and contain, as a weight percentage of oxides, 60 to 70% SiO, 13 to 22% AlO, 0 to 9% BO, 1 to 6% MgO, 0 to 5% CaO, 1 to 5% BaO, 2 to 12% ZnO, and 0 to 3% SrO, wherein AlO+BO+ZnO>23% and BO+MgO−CaO−BaO−SrO<6%. The glasses exhibit a low coefficient of thermal expansion (CTE) and strong acid and alkali durabilities, and may be used in substrates for induction cooktops.
