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...

[0003] The strength of glass-ceramics in the prior art is not very good, and further improvement is still needed. Chinese patent literature (publication number: CN104445952B) discloses a high-hardness transparent glass-ceramics, which contains the following components by weight percentage: Silicon 50%~69.6%, aluminum oxide 15%~25%, magnesium oxide 5~10%, yttrium oxide 0.1%~0.3%, zirconium dioxide 6%~7%, zinc oxide 3%~8% , 0.2% to 0.8% of antimony trioxide, 1% to 3% of diboron trioxide and 0.1% to 0.4% of phosphorus pentoxide. The invention also discloses a preparation method of high-hardness transparent glass-ceramics. The glass-ceramics With the conventional raw material ratio, the strength performance can be further improved. In addition, different temperature control has a great influence on the performance of glass-ceramic

[0004] Chinese patent document (publication number: CN108059347A) discloses a glass-ceramic prepared by electrolytic manganese slag, the raw material of the glass-ceramic prepared by electrolytic manganese slag mainly includes the following components in parts by weight: electrolytic manganese slag 65 -93 parts, 10-20 parts of phosphate rock, 5-16 parts of granite, 23-35 parts of silica lime, 11-22 parts of fly ash, 10-18 parts of mica, 4-12 parts of carbon, 3-10 parts of borax , 8-14 parts of magnesite, 4-15 parts of heavy calcium, and 1-4 parts of zirconia; the raw materials between the glass-ceramics use a combination of various mineral raw materials, and the strength cannot be improved very well
