Title (EN) ALKALI-FREE GLASS
(FR) VERRE NON ALCALIN
(JA) 無アルカリガラス
Abstract:
(EN) The present invention relates to an alkali-free glass which satisfies both a high Young's modulus and a high specific modulus, specifically, an alkali-free glass which comprises in mass% on an oxide basis 40-61 SiO2, 15-23.5 Al2O3, 2-20 MgO, and 0.1-40 CaO, and [SiO2]+0.43×[Al2O3]+0.59×[CaO]-74.6≤0 and [SiO2]+0.21×[MgO]+1.16×[CaO]-83.0≤0.
(FR) La présente invention concerne un verre non alcalin qui satisfait à la fois un module de Young élevé et un module d'élasticité spécifique élevée, plus particulièrement un verre non alcalin qui comprend sur une base d'oxyde 40 à 61% en masse de SiO2, 15 à 23,5% en masse d'Al2O3, 2 à 20% en masse de MgO, et 0,1 à 40% en masse de CaO, et [SiO2]+0,43×[Al2O3]+0,59×[CaO]-74,6≤0 et [SiO2]+0,21×[MgO]+1,16×[CaO]-83≤0.
(JA)  本発明は、高ヤング率および高比弾性率を同時に満たす無アルカリガラスに関し、具体的には酸化物基準の質量%表示で、SiO2 40~61、Al23 15~23.5、MgO 2~20、CaO 0.1~40を含有し、[SiO2]+0.43×[Al23]+0.59×[CaO]-74.6≦0、かつ、[SiO2]+0.21×[MgO]+1.16×[CaO]-83.0≦0である無アルカリガラスに関する。
