Title:
軟化点が低い、高速イオン交換可能な無ホウ素ガラス
Document Type and Number:
Japanese Patent JP6774422
Kind Code:
B2
Abstract:
Alkali aluminosilicate glasses that exhibit fast ion exchange performance and having low softening points that enable the glasses to be formed into non-planar, three-dimensional shapes. The glasses contain less than about 1 mol % of boron oxide and, in some embodiments, are substantially free of B2O3. Furthermore, these glasses have excess amounts of alkali oxides relative to both Al2O3 and P2O5, in order to improve melting behavior and ion exchange performance while still achieving sufficiently low softening points to allow for formability.
