Abstract

The invention discloses microcrystalline glass, a microcrystalline glass product and a manufacturing method of the microcrystalline glass product. The main crystalline phase of the microcrystalline glass contains lithium silicate and a quartz crystal phase, the haze of the microcrystalline glass with the thickness of 0.55 mm is 0.6% or below, and the microcrystalline glass comprises the followingcomponents (by weight): 65-85% of SiO2, 1-15% of Al2O3, 5-15% of Li2O, 0.1-10% of ZrO2, 0.1-10% of P2O5, 0-10% of K2O, 0-10 % of MgO, and 0-10% of ZnO. The microcrystalline glass and the microcrystalline glass product disclosed by the invention have the advantages of crash resistance, compression resistance and scratch resistance, and can meet the requirements of manufacturing cover plate materials on mechanical properties.

Description

technical field [0001] The present invention relates to a glass-ceramic, a glass-ceramic product and a manufacturing method thereof. In particular, the invention relates to a glass-ceramic, a glass-ceramic product and a manufacturing method thereof having excellent mechanical properties suitable for electronic equipment or display equipment. Background technique [0002] Glass-ceramics is a material in which crystals are precipitated inside the glass by heat-treating the glass. Glass ceramics can have physical properties that cannot be obtained in glass due to crystals dispersed inside. For example, for mechanical strength such as Young's modulus and fracture toughness, etching properties for acidic or alkaline liquids, thermal properties such as thermal expansion coefficient, rise and disappearance of glass transition temperature, etc. Glass-ceramics has higher mechanical properties, and due to the formation of crystallites in the glass, its bending resistance and wear res...
