Abstract: There is disclosed a lithium aluminosilicate glass body encased within, and integral with, a thin, compressive, semicrystalline layer containing beta-eucryptite and/or beta-quartz solid solution crystals, and a method of producing such body. The layer has a substantially lower thermal coefficient of expansion than the glass, but has the same chemical composition as the glass. That composition, in percent by weight on a calculated oxide basis is 55-67% SiO2, 5.0-7.5% Li20, 22-28% A1203, 0-2% Na2O and 0-10% ZnO, the molar ratio of R20+R0 to A1203 being greater than one. Controlled crystallization procedure is described whereby the crystallized layer can be produced in a relatively short time.

Abstract: This invention is directed to the production of unitary, transparent glass articles demonstrating exceptionally high flexural and impact strengths composed of an interior portion and an integral surface compression layer. The articles are prepared by contacting glass bodies consisting essentially, in mole percent, of 14-24% R2O, wherein R2O consists of 0-5% Li2O, 0-5% K2O, and the remainder Na2O, 17-21% Al2O3, 45-60% SiO2, 3-6% TiO2 and/or ZrO2, and 0-2% P2O5, the sum of those components constituting at least 85% of the total composition, at a temperature above the annealing point of the glass with a source of Li+ ions to replace at least part of the Na+ ions and, if present, K+ ions in a surface layer with a corresponding amount of Li+ ions and to react the Li+ ions with Al2O3 and SiO2 in the surface layer to form crystallites of beta-quartz solid solution nucleated by the TiO2 and/or ZrO2.
