Abstract

The invention provides glass ceramic with abrasion resistance prepared by adopting industrial wastes. In the invention, chromic oxide is taken as a nucleating agent, and nickel sulfide and magnesium diboride can intensify a nucleating effect of chromic oxide, so as to further reduce interface energy, so that the nucleation activation energy is reduced, and the formation of a crystal form is facilitated. Nickel sulfide and magnesium diboride are matched with other ingredients, so that a glass ceramic plate with excellent abrasion resistance and acid and alkali resistance can be prepared. With adoption of a production process provided by the invention, the abrasion resistance of the prepared glass ceramic plate can be further improved, the porosity defect can be reduced, and the surface porosity is decreased.

Description

technical field [0001] The invention relates to a glass-ceramic, in particular to a wear-resistant glass-ceramic prepared from industrial waste. Background technique [0002] Glass-ceramics, also known as ceramic glass, has dual characteristics of glass and ceramics; glass-ceramics is composed of crystals, and its atomic arrangement is regular. Therefore, glass-ceramics has higher brightness than ceramics and stronger toughness than glass. Glass-ceramics combines the triple advantages of glass, ceramics and natural stone, and is superior to natural stone and ceramics. It can be used in building curtain walls and indoor high-end decoration, becoming an ideal substitute for high-grade stone. At the same time, it can also be used in chemical industry, communication, machinery and other fields. [0003] Architectural decorative glass-ceramic is used as a new type of building material in an increasingly wide range of applications. Glass-ceramic products for construction have th...
