Title (EN) GLASS COMPOSITION
(FR) COMPOSITION DE VERRE
(JA) ガラス組成物
Abstract: front page image
(EN)A glass composition which is reduced in the amount of residual bubbles and is produced using smaller amounts of arsenic oxide and antimony oxide, which impose a heavy burden on the environment. This glass composition comprises, in terms of mass%: 40-70% SiO2; 5-20% B2O3; 10-25% Al2O3; 0-10% MgO; 0-20% CaO; 0-20% SrO; 0-10% BaO; 0.001-0.5% Li2O; 0.01-0.5% Na2O; 0.002-0.5% K2O; and 0-1.0%, excluding 0%, Cl.
(FR)Composition de verre comportant une quantité réduite de bulles résiduelles et produite en utilisant des quantités plus faibles d’oxyde d’arsenic et d’oxyde d’antimoine, qui imposent une lourde charge sur l'environnement. Une telle composition de verre comporte, en pourcentages massiques : 40-70% de SiO2; 5-20% de B2O3; 10-25% d’Al2O3; 0-10% de MgO; 0-20% de CaO; 0-20% de SrO; 0-10% de BaO; 0,001-0,5% de Li2O; 0,01-0,5% de Na2O; 0,002-0,5% de K2O; et 0-1,0%, 0% exclu, de Cl.
