Problems solved by technology

Because the glass-ceramic contains a certain amount of crystals, it will increase the haze of the glass and reduce the transmittance of the glass, which is not conducive to the use of equipment that requires high transmittance.

Abstract

The invention provides a glass-ceramic product which comprises the following components in percentage by weight: 50-59.5% of SiO2, 15-25% of Al2O3, 4-10% of Li2O, 5-15% of Na2O, 0.1-10% of P2O5 and 0-10% of ZrO2. Through reasonable component design, the glass-ceramic product provided by the invention has high transmittance and low haze, and is suitable for electronic equipment or display equipment.

Description

technical field [0001] The invention relates to a glass-ceramic product and a glass-ceramic, in particular to a high-transmittance, low-haze glass-ceramic product, the glass-ceramic and a manufacturing method thereof. Background technique [0002] Glass-ceramic is a material in which crystals are precipitated inside the glass by heat treatment of the matrix glass. It has higher mechanical properties than the matrix glass, and due to the formation of crystallites in the glass, its toughness, wear resistance, etc. The glass has obvious advantages, and further through chemical strengthening to obtain higher strength. [0003] Based on the above advantages, glass-ceramic or glass-ceramic products are currently used in display devices or electronic devices that require high drop resistance, compression resistance, and scratch resistance. Because the glass-ceramic contains a certain content of crystals, it will increase the haze of the glass and reduce the transmittance of the gl...
