Abstract The purpose of the present invention is to provide a lithium aluminosilicate glass having excellent manufacturing properties and strength. The present invention relates to a glass containing, in terms of oxides, 60-70 mol% of SiO2, 10-15 mol% of Al2O3, 8-14 mol% of LiO2, 1-7 mol% of Na2O, 0-5 mol% of K2O, 0-5 mol% of Y2O3, and 0-5 mol% ZrO2, wherein the total content of MgO and CaO is 0.1-7 mol%, the ratio of ZrO2 to the total content of ZrO2 and Y2O3 is 0.30 to 0.70, and the glass has an lnW value of 10-20. Le but de la présente invention est de fournir un verre d'aluminosilicate de lithium ayant d'excellentes propriétés de fabrication et une excellente résistance. La présente invention concerne un verre contenant, au niveau des oxydes, 60 à 70 % molaire de SiO2, 10 à 15 % molaire d'Al2O3, 8 à 14 % molaire de LiO2, 1 à 7 % molaire de Na2O, 0 à 5 % molaire de K2O, 0 à 5 % molaire d'Y2O3, et 0 à 5 % molaire de ZrO2, la teneur totale en MgO et en CaO étant de 0, 1 à 7 % molaire, le ratio de ZrO2 à la teneur totale en ZrO2 et Y2O3 est compris entre 0,30 et 0,70, et le verre présente une valeur lnW de 10 à 20. 製造特性および強度に優れるリチウムアルミノシリケートガラスの提供を目的とする。酸化物基準のモル百分率表示で、SiO2を60~70%、Al2O3を10~15%、LiO2を8~14%、Na2Oを1~7%、K2Oを0~5%、Y2O3を0~5%、ZrO2を0~5%含有し、MgOおよびCaOの含有量の合計が0.1~7%、ZrO2およびY2O3の含有量の合計に対するZrO2の比が0.30以上0.70以下であって、lnWの値が10以上、20以下であるガラスに関する。
