Abstract: A glass composition including 65 to 72 wt-% SiO2, at least 10.1 wt-% Li2O, at least 10.1 wt-% Al2O3, 0 to 2 wt-% K2O, at most 4 wt-% Na2O, 0 to 1.5 wt-% CaO, 0 to 1.5 wt-% CeO2, 1 to 5 wt-% P2O5, 0 to 0.5 wt-% V2O5, 0 to 1 wt-% Ag, and 0 to 1 wt-% ZrO2, based on a total weight of the composition. The composition is devoid of TiO2, Cu2O, BaO, Sb2O3, Nb2O5, MgO, La2O3, and SnO2. The proportion of Li2O to Al2O3 in the composition is in a range of from 1:1 to 1.5:1.

Abstract: A process for preparing glass-ceramic body including the steps of providing a basic glass body and subjecting the basic glass body to a thermal treatment whereby a crystalline phase embedded in a glass matrix is formed. The basic glass body is made of a composition comprising 65 to 72 wt-% SiO2, at least 10.1 wt-% Li2O and at least 10.1 wt-% Al2O3 based on the total weight of the composition, the proportion of Li2O to Al2O3 being from 1:1 to 1.5:1. The thermal treatment involves a nucleation step followed by several crystallization steps at different temperatures, whereby at least two different crystalline phases are formed.

Abstract translation: 一种制备玻璃陶瓷体的方法，包括以下步骤：提供碱性玻璃体，并对基体玻璃体进行热处理，由此形成嵌入玻璃基质中的结晶相。 基本玻璃体由基于组合物总重量的65至72重量％SiO 2，至少10.1重量％的Li 2 O和至少10.1重量％的Al 2 O 3的组合物制成，Li 2 O与Al 2 O 3的比例来自 1：1至1.5：1。 热处理涉及成核步骤，然后在不同温度下进行几个结晶步骤，由此形成至少两个不同的结晶相。
