Abstract

The invention provides eucryptite microcrystal glass and a preparation method thereof. The eucryptite microcrystal glass is prepared from, by weight, 45-70% of eucryptite, 1-5% of lepidolite, 20-38% of quartz sand, 2-8% of aluminum oxide, 3-5% of zirconium oxide and titanium oxide, 0.2-0.8% of talcum, 1-3% of barium carbonate, 0.2-0.7% of antimony trioxide and 0-1.5% of zinc oxide. The Sinkiang eucryptite is used as a main material, and the transparent eucryptite microcrystal glass with low expansion is prepared through synergistic effects of raw materials while indexes of strength, hardness,wear resistance and the like reach utilization standards; on the one hand, the resource utilization rate of domestic eucryptite is increased; on the other hand, microcrystal glass production cost is sharply reduced, getting rid of limitation of foreign imported resources on the industry of lithium-aluminum-silicon microcrystal glass is realized, and accordingly further development of the domesticindustry of lithium-aluminum-silicon microcrystal glass is effectively promoted.

Description

technical field [0001] The invention relates to the technical field of glass-ceramics, in particular to a eucryptite glass-ceramics and a preparation method thereof. Background technique [0002] Glass-ceramics can also be called glass-ceramics, which means that the basic glass is obtained by firing a specific composition formula, and then it is subjected to a certain heat treatment process under a certain temperature system, so that the crystal nucleating agent in the basic glass passes through various The effect is to precipitate a large number of tiny crystalline phases that are evenly distributed with the glass phase in the glass, thereby obtaining a polycrystalline composite solid material with a special structure. [0003] Among them, the expansion coefficient of lithium aluminum silicon (LAS) glass-ceramics is very low, which belongs to the category of low expansion and ultra-low expansion, and can be used in (-5×10 -7 / °C)—(+80×10 -7 / °C) can be adjusted arbitraril...
