Li2O-Al2O3-SiO2 crystallized glass and method of its production

摘要

Li2O-Al2O3-SiO2 crystallized glass is provided which has clarity and glass characteristics equivalent to or superior to a conventional crystallized glass, even when the content of As2O3 is decreased. The Li2O-Al2O3-SiO2 crystallized glass contains, by weight, 0.05 to 4% Sb2O3, wherein the content of beta -OH is 0.3 to 4/mm, and a beta -quartz solid solution or a beta -spodumene solid solution is produced as a main crystal.
