摘要：
The present invention is directed at a family of glasses capable of absorbing UV radiation and filtering yellow light in the visible region of the spectrum, the family of glasses having a composition consisting essentially, in terms of weight percent on the oxide basis, of: 55-95.7% SiO 2 , 0-28% B 2 O 3 , 0.5-18% Al 2 O 3 , 0-4% SrO, 0-13% BaO, 0-13% CaO, 0-8% MgO, 0-7.5% Na 2 O, 0-9.5% K 2 O, 0-1.5% Li 2 O, 0-1.5% Sb 2 O 3 , 0.4-4.5% Nd 2 O 3 , and 0.1-1% CeO 2 . Glasses of the present invention are capable of employment as envelopes for tungsten-halogen lamps and other high temperature light sources, as well as sealed-beam incandescent headlights.
