Microcrystalline glass and preparation method thereof

Abstract

The invention relates to a kind of microcrystalline glass and a preparation method thereof. The preparation raw materials include 10-90wt% of iron, vanadium and titanium-containing tailings, 5-50wt% of fluorite tailings, 1-50wt% of dolomite and 0-20wt% of soda ash. The preparation method of the microcrystalline glass comprises the following steps: uniformly mixing and fusing raw materials in proportion so as to obtain fused glass fluid; and shaping the fused glass fluid, then cooling the shaped glass fluid, and carrying out heat treatment on the obtained product so as to obtain the microcrystalline glass. The microcrystalline glass provided by the invention can be widely used for manufacturing high wear-resisting, acid and alkali erosion resistant and impact resistant products, and the performance of the microcrystalline glass is far higher than that of cast stone, thereby not only solving the pollution problem of tailings and manufacturing high-technical-content and high value-added products.

Description

technical field

[0001] The invention relates to a glass-ceramic and a preparation method thereof, in particular to a glass-ceramic prepared by using Chengde vanadium-containing titanium magnet tailings and fluorite tailings and a preparation method thereof. Background technique

[0002] The building materials with high wear resistance, acid and alkali corrosion resistance and impact resistance are now widely used cast stone, which is a processed silicate crystal material. However, at present, cast stone is mainly formed by melting and casting basalt or diabase, and it is necessary to mine basalt or diabase, which will damage the surrounding environment. Microcrystalline glass, also known as microcrystalline jade or ceramic glass, is a comprehensive glass and a new type of building material newly developed by foreign countries. Its scientific name is glass crystal. Glass-ceramic looks very different from our usual glass. It has the dual characteristics of glass and ceramics...
