摘要
A Co- or (Co + Ni)-coloured phosphate glass which is used as the basis for optical coloured and filter glasses and whose solarisation tendency in the light wavelength range around lambda 254 is particularly reduced comprises (in % by weight): P2O5 64-80; SiO2 0-7.5; B2O3 0.5-5.5; Al2O3 3.5-15; Li2O 0-1.5; Na2O 0-2.5; K2O 0-10; BaO 0-12; BaCl2 0-2.5; CaO 0-5; CaCl2 0-2.5; SrO 0-5; MgO 0-3.5; ZnO 0-6; PbO 0-3; Co 0-2; Ni 0-1.75; Fe 0-3.8; Ge 0-2; Sn 0-1.5; Ce2O3 0-2.5.
