Cadmium-free and lead-free glass compositions, thick film formulations containing them and uses thereof

摘要

A glass composition comprising, in mole percent of the total composition:glass-forming compounds in a total amount of 75 to 85%, wherein said glass forming compounds comprise 40 to 65% SiO2, 10 to 20% Bi2O3 and 0.1 to 3% Al2O3, andglass modifiers in a total amount of 15 to 25%, wherein said glass modifiers comprise 1 to 23 % ZnO, 0.1 to 5% CuO, 0.1 to 5 CaO and 0.1 to 2% MgO, thick film formulations containing said composition and uses thereof.
