Problems solved by technology

Due to the high gloss on the surface of glass-ceramic, it is easier to show scratches than polished tiles, and the Mohs hardness of glass-ceramic can only reach level 6, so glass-ceramic is easy to be scratched and wear-resistant. Low, this shortcoming limits the application of glass-ceramic to a great extent, for example, ordinary glass-ceramic is not suitable for paving the ground in a large area

Description

technical field [0001] The invention relates to a glass-ceramic, in particular to a high-transparency wear-resistant and corrosion-resistant glass-ceramic and a preparation method thereof. Background technique [0002] Glass-ceramics refers to the basic glass of specific components, a type of composite material containing a large number of crystalline phases and glass phases, which has glass properties and ceramic properties, and is prepared by controlling crystallization during the heating process. Since its inception, glass-ceramic has been favored by many scientific researchers because of its adjustable composition and designable functions. The distribution of the glass phase and the crystalline phase varies with their ratio: when the proportion of the glass phase is large, the glass phase is a continuous matrix, and the crystal phase is evenly distributed in it; when the glass phase is small, the glass phase is dispersed Between the crystal grids, it is a continuous net...
