Abstract

The invention discloses a preparation method of imitation jade microcrystalline glass. The method comprises the following steps of 1, raw material selection; 2, raw material mixing; 3, mixed materialmelting; 4, calendaring shaping; 5, annealing; 6, crystallization. The method can be used for producing imitation jade microcrystalline glass applicable to ground, wall surface and tabletop decoration. Meanwhile, a microcrystalline glass imitation jade product has the characteristics of acid and alkali resistance and color fastness. The advantages cannot be reached by other products. In the production process, imitation jade microcrystalline glass in various color series can be prepared by controlling the consumption of granite and changing the coloring iron ion content.

Description

technical field [0001] The invention relates to a method for preparing glass-ceramics, in particular to a method for preparing imitation jade glass-ceramics. Background technique [0002] Glass-ceramic not only has the basic properties of glass, but also has the polycrystalline characteristics of ceramics. It combines the characteristics of glass and ceramics and becomes a unique new type of material. Because of its high mechanical strength, high hardness, good wear resistance, strong corrosion resistance, good chemical stability and thermal stability, and can adapt to harsh environments, it has developed rapidly in the world in recent years. In particular, in the "Twelfth Five-Year New Material Industry Development Plan", calendered glass-ceramic is included in the catalog of new inorganic non-metallic materials that are to be developed, which has important guiding significance for the application of calendered glass-ceramics in the field of basic new materials in the futur...
