Embodiment Construction

[0189] The invention is illustrated by the following examples.

[0190] For some examples, the composition and properties of the crystallizable starting glass for transparent glass-ceramics are shown in Table 1. Here, glasses 1 to 3 are glasses according to the invention, whereas glass 4 is a comparative glass outside the scope of the invention. Table 2 shows the composition and properties of the crystallizable starting glasses for transparent colored glass-ceramics. Here, glasses 5 to 11 are glasses according to the invention, whereas glass 12 is a comparative glass outside the scope of the invention. Due to the impurities typical in industrial mixtures of the raw materials used, the composition does not add up to exactly 100% by weight. Although not intentionally introduced into the composition, typical impurities are F, Cl, B, P, Rb, Cs, Hf or Sr, which are usually present in amounts below 0.05% by weight. They are usually introduced via the raw materials used for the re...

Abstract

The invention relates to transparent or transparent dyed lithium aluminium silicate (LAS) glass ceramic material having an adapted thermal expansion, consisting of a glass ceramic material comprising high-quartz mixed crystals as the predominant crystalline phase, and a thermal expansion between room temperature and 700 DEG C from 1.0 to 2.5 10-6 / K, preferably from 1.3 to 1.8 10-6 / K.

Description

technical field [0001] The present invention relates to transparent or transparent colored lithium aluminosilicate (LAS) glass-ceramic materials having adapted thermal expansion and consisting of glass-ceramics comprising a high-temperature / β-quartz solid solution as the main crystalline phase, and to uses thereof. Background technique [0002] It is well known that the Li 2 O-Al 2 o 3 -SiO 2 The glass in the system is transformed into a glass-ceramic product having β-quartz solid solution and / or keatite solid solution as the main crystal phase. [0003] The main property of these glass-ceramic articles with β-quartz solid solution as the main crystalline phase is the ability to manufacture materials with a very low coefficient of thermal expansion in the defined temperature range. Usually, the thermal expansion characteristics are set so that the material has zero thermal expansion, usually 0±0.3·10 in the range of its service temperature -6 / K. Thus, for example, the...
