Abstract: front page image
(EN)A lead-free SiO2-B2O3-ZnO-R2O-CuO based glass having a low melting point (a first glass), which has transparency and insulating property, and comprises, in wt %, 7 to 20 % of SiO2, 32 to 50 % of B2O3, 25 to 42 % of ZnO, 7 to 20 % of R2O (Li2O + Na2O + K2O), 0.1 to 2 % of CuO, and 0 to 10 % of RO (MgO + CaO + SrO + BaO); and a lead-free SiO2-B2O3-ZnO-R2O-CuO based glass having a low melting point (a second glass), which has transparency and insulating property, and comprises, in wt %, 11 to 20 % of SiO2, 45 to 65 % of B2O3, 10 to 20 % of ZnO, 10 to 18 % of R2O (Li2O + Na2O + K2O), and 0.1 to 2 % of CuO.
(FR)Un verre à base de SiO2-B2O3-ZnO-R2O-CuO sans plomb présentant un point de fusion bas (un premier verre), lequel présente une propriété de transparence et d'isolement et comprend, en % en poids, 7 à 20 % de SiO2, 32 à 50 % de B2O3, 25 à 42 % de ZnO, 7 à 20 % de R2O (Li2O + Na2O + K2O), 0,1 à 2 % de CuO et 0 à 10 % de RO (MgO + CaO + SrO + BaO) ; et un verre à base de SiO2-B2O3-ZnO-R2O-CuO sans plomb présentant un point de fusion bas (un second verre), lequel présente une propriété de transparence et d'isolement, et comprend, en % en poids, 11 à 20 % de SiO2, 45 à 65 % de B2O3, 10 à 20 % de ZnO, 10 à 18 % de R2O (Li2O + Na2O + K2O) et 0,1 à 2 % de CuO.
(JA) 本発明は、透明絶縁性を有し、重量%でSiO2を7~20、B23を32~50、ZnOを25~42、R2O(Li2O+Na2O+K2O)を7~20、CuOを0.1~2、RO(MgO+CaO+SrO+BaO)を0~10含むSiO2-B23-ZnO-R2O-CuO系無鉛低融点ガラス(第1ガラス)に関する。さらに、本発明は、透明絶縁性を有し、重量%でSiO2を11~20、B23を45~65、ZnOを10~20、R2O(Li2O+Na2O+K2O)を10~18、CuOを0.1~2含むSiO2-B23-ZnO-R2O-CuO系無鉛低融点ガラス(第2ガラス)に関する。
