CRYSTALLIZABLE GLASS, CRYSTALLIZED GLASS, CRYSTALLIZED GLASSARTICLE, AND METHOD OF MANUFACTURING THE CRYSTALLIZED GLASS ARTICLE |
摘要 |
A crystallized glass which can be redraw-molded and a process for producing a crystallized glass article by redraw-molding. In the crystallize d glass, the maximum particle size of the deposited crystals is 5 .mu.m or bel ow and the glass phase amounts to 10 to 85 % by volume. It has a softening poin t lower than the melting point of the main deposited crystals and its crystallization does not proceed substantially, even when it is heated to a temperature higher than the softening point. A redraw-molded crystallized glass article may be produced by premolding the above-mentioned crystallized glass and then orienting it while heating to a temperature high er than the softening point.
