Mixed glaze of colored frit glass

Abstract

Abstract PURPOSE: To obtain mixed glaze of colored frit glass having a low coefft. of thermal expansion, capable of being calcined at a low temp., and producing a favorable coloring effect by mixing colored frit glass contg. B 2 O 3 as an essential component with a specified oxide. CONSTITUTION: To ≥90% basic composition consisting of 0W30% SiO 2 , 30W60% B 2 O 3 , 0W60% ZnO, 0W7% Li 2 O+Na 2 O+K 2 O, 10W30% MgO+CaO+SrO+ BaO, 0W30% PbO and 0W10% Al 2 O 3 are added Fe 2 O 3 , Ca 2 O 3 , MnO and Cu 2 O as principal colorants by 0.5W10% in total, and ≥50 parts of this colored frit glass are mixed with one or more among TiPbO 3 , SiO 2 , Al 2 O 3 , 2SiO 2 and ZrSiO 4 as the balance. By this composition the desired mixed glaze of colored frit glass having ≥50×10 -7 cm/cm/°C coefft. of thermal expansion and capable of being calcined at ≤700°C is obtd. COPYRIGHT: (C)1982,JPO&Japio
