GLASS COMPOSITION FOR COVERING ELECTRODES AND GLASS PASTE CONTAINING THE SAME

摘要

A glass composition for covering electrodes of the present invention contains: 0 to 15 wt % SiO₂; 10 to 50 wt % B₂O₃; 15 to 50 wt % ZnO; 0 to 10 wt % Al₂O₃; 2 to 40 wt % Bi₂O₃; 0 to 5 wt % MgO; 5 to 38 wt % CaO+SrO+BaO; 0 to 0.1 wt % Li₂O+Na₂O+K₂O; 0 to 4 wt % MoO₃; and 0 to 4 wt % WO₃, and the total of the contents of MoO₃ and WO₃ is in the range of 0.1 to 8 wt %. The glass composition for covering electrodes of the present invention may contain: 0 to 2 wt % SiO₂; 10 to 50 wt % B₂O₃; 15 to 50 wt % ZnO; 0 to 10 wt % Al₂O₃; 2 to 40 wt % Bi₂O₃; 0 to 5 wt % MgO; 5 to 38 wt % CaO+SrO+BaO; 0 to 4 wt % MoO₃; and 0 to 4 wt % WO₃, and the total of the contents of MoO₃ and WO₃ may be in the range of 0.1 to 8 wt %.
