Abstract

863,500. Sealing glass compositions. CORNING GLASS WORKS. March 16, 1959 [March 24, 1958], No. 9042 /59. Class 56. At least 95% by weight of a sealing glass consists of 75 to 82% PbO, 6À5 to 12% of B 2 O 3 , 7 to 14% of ZnO, 1À5 to 3% of SiO 2 and 0 to 3% of Al 2 O 3 . It has a softening point not over 385‹C., is capable of thermal devitrification within an hour at about 450‹C. and is compatible with materials having thermal expansion coefficients within a range of 80 to 105 x 10<SP>-7</SP>. Other oxides which may be included are BaO, CaO, FezOs and at least one alkali metal oxide e.g. Na 2 O with Li 2 O. Eight examples are given. Specification 822,272 is referred to.
