Abstract

The invention provides a high-silicon jade-liked microcrystalline glass. The high-silicon jade-liked microcrystalline glass comprises following ingredients, by weight, 75 to 80% of silicon dioxide, 13 to 25% of aluminum oxide, 7 to 12% of sodium oxide, and the balance boron oxide. The high-silicon jade-liked microcrystalline glass looks like semitransparent jade; possesses smooth feel and wax feel of natural jade. Composition proportion is simplified, cost is reduced, and at the same time high toughness and high strength of microcrystalline glass are ensured. The high-silicon jade-liked microcrystalline glass is convenient for further machine shaping; and can be widely used in the fields of substitute goods of high-grade stone.

Description

technical field [0001] The invention relates to the field of glass-ceramics, in particular to a high-silicon jade-like glass-ceramic. Background technique [0002] With the steady and continuous development of my country's national economy, people's living standards are improving, and the demand for high-grade building materials is increasing, especially the demand for alternative products of non-radiation high-grade stone is more urgent, but domestic high-grade stone substitute products are brittle. It is not easy to process and shape, so many high-grade stone materials need to be imported from abroad, and the cost is greatly increased. [0003] Glass-ceramics, also known as ceramic glass, has dual characteristics of glass and ceramics. Glass-ceramics is composed of crystals with regular atomic arrangements. Therefore, glass-ceramics has higher brightness than ceramics and stronger toughness than glass. Glass-ceramic combines the triple advantages of glass, ceramics and nat...
