Title (EN) NON-ALKALINE GLASS AND METHOD FOR PRODUCING SAME
(FR) VERRE NON ALCALIN ET SON PROCÉDÉ DE PRODUCTION
(JA) 無アルカリガラスおよびその製造方法
Abstract:
(EN) The present invention addresses the problem of providing: a non-alkaline glass that contains a refining agent and rarely undergoes the occurrence of reboiling during stirring; and a method for producing the non-alkaline glass. The present invention relates to a non-alkaline glass which satisfies specific properties and a specified glass composition, contains SnO2 in an amount of 0.05 to 1% by weight, has a total sulfur content of 0.5 to 25 ppm by weight in terms of SO3 content, and also has an S2- content of 3 ppm by weight or less as measured after cooling a molten product, which is produced by melting the non-alkaline glass at 1500 to 1800°C, to 600°C or lower within 1 minute or shorter.
(FR) La présente invention aborde le problème consistant à fournir : un verre non alcalin qui contient un agent de raffinage et qui subit rarement l'apparition de rebouillage pendant l'agitation; et un procédé de production du verre non alcalin. La présente invention concerne un verre non alcalin qui satisfait des propriétés spécifiques et une composition de verre spécifiée, contient du SnO2 en une quantité de 0,05 à 1 % en poids, a une teneur totale en soufre de 0,5 à 25 ppm en poids en termes de teneur en SO3, et a également une teneur en S2- de 3 ppm en poids ou moins telle que mesurée après refroidissement d'un produit fondu, qui est obtenu par fusion du verre non alcalin entre 1 500 et 1 800 °C, à 600 °C ou moins en 1 minute ou moins.
(JA) 本発明は清澄剤を含有し且つ撹拌リボイルが発生しにくい無アルカリガラスおよびその製造方法を提供することを課題とする。本発明は、特定の特性及びガラス組成を満たし、さらに、SnOを0.05~1重量%含有し、SO換算した全硫黄含有量が0.5~25重量ppmであり、かつ、1500~1800℃で溶融した状態から1分間以内で600℃以下にまで冷却した後に測定されるS2-含有量が3重量ppm以下である無アルカリガラスに関する。
