Abstract

1,233,512. Glass composition. CARLZEISS - STIFTUNG, trading as JENAER. GLASWERK SCHOTT & GEN.]. 18 March, 1969 [30 March, 1968], No. 14137/69. Heading C1M. A glass consists essentially of (in weight per cent): BaO 30-37 TiO 2 45-54 ZrO 2 2-9 La 2 O 3 1-5 WO 3 0-10 Ta 2 O 5 and/or Nb 2 O 5 0-5 ZnO 0-3À0 SiO 2 0-2À7 B 2 O 3 0-2À7 GeO 2 0-1À5 Al 2 O 3 0-1À0 As 2 O 3 0-2À0, where (SiO 2 + B 2 O 3 + Al 2 O 3 ) does not exceed 2À7. The glasses generally have refractive index values, nd, of at least 2À2, and may be used in forming glass beads, which have a slight yellowish colour.
