Title (EN) GLASS COMPOSITION FOR LAMP, GLASS PART FOR LAMP, AND PROCESS FOR PRODUCING LAMP OR GLASS COMPOSITION FOR LAMP
(FR) COMPOSITION DE VERRE POUR LAMPE, PARTIE EN VERRE POUR LAMPE ET PROCÉDÉ DE PRODUCTION DE LAMPE OU DE COMPOSITION DE VERRE POUR LAMPE
(JA) ランプ用ガラス組成物、ランプ用ガラス部品、ランプおよびランプ用ガラス組成物の製造方法
Abstract: front page image
(EN)A glass composition for lamp comprising, by weight percentage, 60 to 75% SiO2, 0.01 to 5.2% CeO2+Ce2O3, 0.01 to 5.2% SnO+SnO2, 0.5 to 6% Al2O3, 0 to 5% B2O3, 13 to 20% Li2O+Na2O+K2O, 0.5 to 5% MgO, 1 to 10% CaO, 0 to 10% SrO, 0 to 10% BaO, 0 to 10% ZnO, 0 to 0.2% Fe2O3+FeO and 0 to 1% TiO2. This provides a glass composition for lamp that does not contain lead and antimony and that has high ultraviolet screening capacity, ensuring less occurrence of glass initial staining and ultraviolet-caused staining.
(FR)La présente invention concerne une composition de verre pour lampe comprenant, en pourcentage en poids, de 60 à 75 % de SiO2, de 0,01 à 5,2 % de CeO2 + Ce2O3, de 0,01 à 5,2 % de SnO + SnO2, de 0,5 à 6 % de Al2O3, de 0 à 5 % de B2O3, de 13 à 20 % de Li2O + Na2O + K2O, de 0,5 à 5 % de MgO, de 1 à 10 % de CaO, de 0 à 10 % de SrO, de 0 à 10 % de BaO, de 0 à 10 % de ZnO, de 0 à 0,2 % de Fe2O3 + FeO et de 0 à 1 % de TiO2. Ceci donne une composition de verre pour lampe qui ne contient ni plomb, ni antimoine et qui présente une capacité élevée de filtrage des ultraviolets, ce qui assure un moindre ternissement initial du verre et un moindre ternissement causé par les ultraviolets.
(JA) 重量百分率で、SiO:60~75 wt%、CeO+CeO:0.01~5.2 wt%、SnO+SnO:0.01~5.2 wt%、AlO:0.5~6 wt%、BO:0~5 wt%、LiO+NaO+KO:13~20 wt%、MgO:0.5~5 wt%、CaO:1~10 wt%、SrO:0~10 wt%、BaO:0~10 wt%、ZnO:0~10 wt%、FeO+FeO:0~0.2 wt%、TiO:0~1 wt%からなるランプ用ガラス組成物とする。これにより、鉛およびアンチモンを含有せず、紫外線遮断能力が高く、かつ、ガラスの初期着色および紫外線による着色が起こり難いランプ用ガラス組成物とすることができる。
