Abstract
869,328. Ceramic glass. CORNING GLASS WORKS. Dec. 22, 1959 [Dec. 30, 1958; Nov. 23, 1959], No. 43558/59. Class 56. A semi-crystalline ceramic body is made by the heat-treatment of glass bodies consisting essentially on molecular per cent basis of 50- 68% SiO 2 ; 16-34% Al 2 O 3 ; 7-34% Na 2 O; 0-15% CaO; 0-6% K 2 O, the total Na 2 O, CaO and K 2 O being 15-34% and the molecular ratio of Na 2 O+CaO+K 2 O: Al 3 O 2 not exceeding 1À7, which comprises including in the glass batch as nucleating agents constituents of compounds forming crystals with ilmenite-type structures in the indicated proportions based upon a molecular per cent in excess over the base glass, selected from the group consisting of 0À08- 0À50% Cr 2 O 3 , and at least one titrate of a divalent metal oxide selected from the group consisting of iron, cobalt, cadmium, zinc, nickel, manganese and magnesium oxides in which the proportion of TiO 2 is between 2À9 and 12%, the proportion of divalent metal oxide is between 1À9 and 10%, the total of the titanate being at least 6% and thereafter heat treating the glass body formed to the desired shape from the molten glass by exposing the body to a temperature between 800‹C. and 1150‹C. for a sufficient time to cause a major proportion of the glass to crystallize. The body may be heated at 800‹C.-850‹C. for about 1 to 4 hours and then at 1000‹C.-1080‹C. for about 6 to 12 hours with or without an intermediate heating step at 900‹C.-950‹C. for about 3 to 8 hours. Magnesium titanate is the preferred nucleating agent. Large numbers of examples are given. The glasses using Co, Fe, Cr, Mn, and Ni are coloured, varying from grey to yellow, blue, green and brown. Specification 829,447 is referred to.
