Title (EN) TEMPERED GLASS
(FR) VERRE TREMPÉ
(JA) 強化ガラス
Abstract:
(EN) The present invention pertains to: a tempered glass which is obtained by physically strengthening a glass having an average thermal expansion coefficient at 50-350ºC of (20 × 10-7)-(50 × 10-7)/)ºC and a glass transition temperature of 560ºC or higher; and a tempered glass obtained by physically strengthening a glass containing, in mole percent on an oxide basis, 0-4% of R2O (R2O is defined in the specification) and 5-25% of B2O3.
(FR) La présente invention concerne : un verre trempé qui est obtenu par renforcement physique d'un verre ayant un coefficient de dilatation thermique moyen compris entre 50 °C et 350 °C de (20 × 10-7)-(50 × 10-7)/)ºC et une température de transition vitreuse supérieure ou égale à 560 °C ; et un verre trempé obtenu par renforcement physique d'un verre contenant, en pourcentage molaire sur une base d'oxyde, de 0 % à 4 % de R2O (R2O est défini dans la description) et de 5 % à 25 % de B2O3.
(JA) 本発明は、50~350℃での平均熱膨張係数が20×10-7~50×10-7/℃であり、ガラス転移点が560℃以上であるガラスが物理強化された強化ガラス、及び、酸化物基準のモル百分率表示で、RO:0~4%(ROは明細書中に規定されている)、及びB:5~25%を含有するガラスが物理強化された強化ガラスに関する。
