Abstract

909,679. Glass compositions. CARL-ZEISSSTIFTUNG, [trading as JENAER GLASWERK SCHOTT & GEN.]. June 15, 1959 [June 13, 1958], No. 20467/59. Class 56. A fluoride-containing phosphate glass free from Be, Na, K and having a low dispersion and a relatively high light refraction is made by melting, with stirring, a batch composed, as to at least 90%, of a metallic fluoride or a mixture of fluorides and a metallic phosphate or mixture of phosphates or phosphate forming substances, the amounts being chosen so that the final glass contains 5-11% by weight of AlF 3 , more than 15% of BaF 2 and/or SrF 2 and at least 20% of metallic phosphate comprising 0-17% of Al(Po 3 ) 3 and/or 0.40% of Ba(Po 3 ) 2 . The batch preferably includes 12% of metaphosphate of Mg, Ba, Al and also at least 8% pyrophosphate of Mg, Sr, Ba and at least 8% orthophosphate of the same metals. The fluorides may include those of Mg, Ca, La, Cd. Up to 10% of Li 2 O, B 2 O 3 , WO 3 or Al 2 O 3 , may also be included.
