Title:
亀裂発生閾値が高いイオン交換可能なガラス
Document Type and Number:
Japanese Patent JP6421950
Kind Code:
B2
Abstract:
Alkali boroaluminosilicate glasses with high resistance to crack initiation and damage due to sharp impact are provided. The glass compositions have melting and forming temperatures that allow forming the glass into sheets via float-based processes while still allowing for the glass to be efficiently ion exchanged. The glass compositions contain MgO, and when ion exchanged, have a Vickers indentation crack initiation load of at least about 10-15 kgf.
