Abstract

The invention relates to high-hardness high-strength high-transparency microcrystalline glass and a preparation method and application thereof. The preparation method comprises the following steps: casting a mixture into glass, and carrying out crystallization treatment to obtain the microcrystalline glass, wherein the mixture mainly comprises Li2O, A2lO3, SiO2, CaO, SrO, ZnO, BaO, K2O, Na2O, ZrO2, Sb2O3 and NaCl; and the prepared microcrystalline glass is mainly composed of a glass matrix, spodumene crystals dispersed in the glass matrix and distributed in a dendritic manner, spinel crystalsdistributed in a granular manner and cubic zirconium oxide crystals distributed in a granular manner, and can be applied to preparation of high-strength wear-resistant transparent microcrystalline glass glaze and to preparation of mobile phone panels. The preparation method of the high-hardness high-strength high-transparency microcrystalline glass is simple and easy to implement, and has extremely high popularization value; and the prepared microcrystalline glass has the advantages of a low melting point, excellent forming processability and good application prospects.

Description

technical field [0001] The invention belongs to the technical field of glass-ceramics, and relates to a glass-ceramic with high hardness, high strength and high transparency, its preparation method and application. Background technique [0002] There are many types of glass-ceramics, and glass products with different uses can be produced by different composition ratios and different processes. Most of the glass-ceramics disclosed in the prior art are architectural decorative materials, biological materials, craft products or small heating products, etc. The glass-ceramics used in the above products in the prior art usually have high strength and hardness, but there is a common problem that the high melting point cannot be processed and formed to prepare wear-resistant glass glazes and mobile phone panels. [0003] Therefore, it is of great significance to study a glass-ceramic with high hardness, high strength and high transparency that can be processed and formed to prepar...
