Preparation method of intensity-improvable glass ceramics

Abstract

The invention discloses a preparation method of intensity-improvable glass ceramics. The method comprises the following step of 1, weighing the following raw materials in corresponding percentage by weight for later use: 32 to 38 percent of SiO2, 26 to 30 percent of Al2O3, 12 to 18 percent of MgO, 0.3 to 0.5 percent of Fe2O3, 14 to 18 percent of electrolytic manganese residue, 0.02 to 0.06 percentof tin phosphorus compounds, 0.01 to 0.05 percent of rare earth elements and 0.01 to 0.03 percent of intensity auxiliary agents. The preparation method of the intensity-improvable glass ceramics hasthe advantages that the intensity of the glass ceramics is greatly improved through being compared with that in the prior art; high use values and good application prospects are realized.

Description

technical field [0001] The invention relates to the technical field of glass-ceramics preparation, in particular to a preparation method of glass-ceramics whose strength can be improved. Background technique [0002] Glass-ceramic refers to the addition of some nucleating substances to the glass, and through heat treatment, light irradiation, or chemical treatment, a large number of tiny crystals are uniformly precipitated in the glass to form a multi-phase dense microcrystalline phase and glass phase. Composite, by controlling the types and sizes of crystallites, transparent glass-ceramics, glass-ceramics with zero expansion coefficient, surface-strengthened glass-ceramics, glass-ceramics of different colors or machinable glass-ceramics can be obtained. Composition of glass phase and crystal phase, the distribution of the two changes with their ratio. When the proportion of glass phase is large, the glass phase is a continuous matrix, and the crystal phase is evenly distrib...
