Abstract
1,268,845. Crystallized glass. NIPPON ELECTRIC GLASS CO. Ltd. 9 July, 1969 [29 July, 1968], No. 34653/69. Heading C1M. Crystallized glass is made from a glass comprising (in weight per cent) to an extent of at least 90%; SiO 2 55-73; Al 2 O 3 15-35; Li 2 O 2-6; ZrO 2 1-4; TiO 2 0À5-3; F 0.01-4; by carrying out a primary heat treatment for 0À5-20 hours between the transformation and softening temperatures of the glass, and then carrying out a secondary treatment by heating up to 850-1200‹ C. #-Encryptite is converted to #-Spodumene in the interior of the glass while remaining unchanged on the surface. The primary heat treatment may be at 700-770‹ C. The glass may be maintained at 850-1200‹ C. for 0-8 hours. The linear expansion coefficient of the crystallized glass is 7-30 x 10
