Abstract
1,204,187. Glass composition. CARLZEISS - STIFTUNG, [trading as JENAER GLASWERK SCHOTT & GEN.]. 13 Dec., 1967 [17 Dec., 1966; 29 April, 1967], No. 56609/67. Heading ClM. A glass with R.I. >1.75 is composed in wt. per cent of: (1) BaO, 0À5-5; La 2 O 3 , 5-65; Al 2 O 3 , 4-25; SiO 2 , 4-25; Nb 2 O 5 , 0À5-81À5; Ta 2 O 3 , 0À5-81À5 ; the glass is free from B 2 O 3 , BeO, or ThO 2 . Preferably (Al 2 O 3 + SiO 2 ) is 12-45%. In (1) Al 2 O 3 may be replaced in whole or part by equivalent proportions of Ga 2 O 3 and/or In 2 O 3 , and, in this case, SiO 2 may be replaced in whole or part by an equivalent proportion of GeO 2 . Such a glass is composed, in wt. per cent, of (2) BaO, 0À5-5; La 2 O 3 , 5-55; Ga 2 O 3 and/or In 2 O a , 5-60; GeO 2 , 4-70; Nb 2 O 5 , 05-65; Ta 2 O 5 , 05-65. Specific examples are given.
