摘要
The crystallization-stable alumino-silicate glass is free of B2O3 and contains 50 to 60% by weight, SiO2; 14 to 25% by weight, Al2O3; 0 to 2% by weight, P2O5; 0 to 7, % by weight, MgO; 5 to 14% by weight, CaO; 0.1-2.0% by weight, SrO; 12.0 to 18% by weight BaO and at least 0.01% by weight MoO3. The glass preferably contains 0.01 wt. % of water. The glass has high transmission in the visible and IR region of the spectrum, which makes it especially suitable for lamps, bulbs for halogen lamps; and also for solar collectors, for flat display screens and for pharmaceutical packages n which the glass functions as a UV-protective glass.
