Title (EN) GLASS
(FR) VERRE
(JA) ガラス
Abstract:
(EN) Provided is a glass which has a small variation in mechanical strength. A glass which is configured such that: at least a part of a surface layer is composed of a chemically toughened layer; and the interior portion of the glass excluding the chemically toughened layer contains P, Al and an alkali metal that is composed of one or both of Li and Na.
(FR) L'invention concerne un verre qui présente une faible variation de résistance mécanique. Un verre est conçu de sorte que : au moins une partie d'une couche de surface est composée d'une couche chimiquement durcie ; et la partie intérieure du verre, à l'exclusion de la couche chimiquement durcie, contient du P, de l'Al et un métal alcalin qui est composé de Li et/ou de Na.
(JA) 機械的強度のばらつきが小さいガラスの提供。表層の少なくとも一部が化学強化層で構成されるガラスであって、前記ガラスは、前記化学強化層を除くガラス内部が、Pと、Alと、LiおよびNaのいずれか一方、もしくは両方からなるアルカリ金属とを含有する、ガラス。
