Description

technical field [0001] The invention relates to the technical field of glass-ceramics, in particular to a glass-ceramic for heat-resistant and corrosion-resistant buildings. 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 present, the waste rate of existing glass-ceramic products is high, especially in the finished glass-ceramic plates, unclosed pores and shrinkage cavities are prone to occur, resulting in a decrease in the mechanical properties of the product, which in turn ...
