Abstract

The invention discloses a method for preparing diopside and feldspar main crystal phase microcrystalline glass, by taking low silicon high calcium magnesium type iron tailings as main raw material and using sintering process. By adding iron tailings to the formulation of microcrystalline glass, the mixed raw materials are melted in hot water and then glass pellets are formed. The glass pellets are laid in a certain way and finally microcrystalline glass mainly comprising of diopside and feldspar is formed after sinterring, crystallizing and shakeouting. The method requires simple process equipment and the addition of iron tailings in the raw materials, which is helpful in reducing dosage of natural raw materials and chemical materials and nucleating agent is no longer in need. The auxiliary components such as Na2O and K2O contained in the iron tailings can reduce the glass melting temperature, which can greatly reduce production costs, meet the market demand of glass ceramics. Meanwhile, the new method can effectively improve environmental problems caused by tailings stacked and it conforms to the national environmental policy.

Description

technical field

[0001] The invention belongs to the technical field of building decoration materials, and in particular relates to a diopside and feldspar main crystal phase glass-ceramics and a preparation method thereof. Background technique

[0002] Glass-ceramics is a kind of polycrystalline solid material containing a large number of microcrystalline phases and glass phases, which is obtained by controlling the crystallization of the base glass with a specific composition during the heating process. Glass-ceramic exhibits excellent properties in terms of mechanical strength, hardness, thermal expansion, chemical stability, optical and electrical properties, and is therefore widely used in the fields of architectural decoration, machinery, optics, electronics, biomedicine, and chemical engineering. Among them, glass-ceramic for architectural decoration is used in the largest amount, and its economic benefits are remarkable. Its decorative effect and physical and chemical...
