Embodiment

[0410] In order to further clearly illustrate and illustrate the technical solution of the present invention, the following non-limiting examples are provided. Efforts have been made to ensure accuracy with respect to values ​​(eg, amounts, temperature, etc.) in the embodiments of the invention, but some errors and deviations must be accounted for. The composition itself is given in weight % based on oxides and has been normalized to 100%.

[0411]

[0412] In this example, the matrix glass having the compositions shown in Table 1 to Table 4 was obtained by using the above-mentioned manufacturing method of the matrix glass. In addition, the characteristics of each matrix glass were measured by the test method described in the present invention, and the measurement results are shown in Tables 1 to 4.

Abstract

The present invention provides a glass ceramic and a glass ceramic product with excellent mechanical properties, the glass ceramic product comprises the following components by weight: 65-80% of SiO2; less than 5% of Al2O3; 10-25% of Li2O; 5-15% of ZrO2; and 1-8% of P2O5, wherein Al2O3 / (Li2O+ZrO2+P2O5) is 0.3 or below. Through reasonable component design, the obtained glass ceramic product has excellent mechanical properties.

Description

technical field [0001] The invention relates to a glass-ceramic, in particular to a glass-ceramic with excellent mechanical properties, a glass-ceramic product and a manufacturing method thereof. Background technique [0002] In recent years, with the continuous rise and development of consumer electronic products, glass, as a transparent material with good performance, has been widely used in such electronic devices. Devices such as LED and LCD displays and computer monitors can have "touch" functionality, which means that the glass used in them must be in contact with various objects, such as the user's finger and / or stylus device. In this way, the glass needs to have sufficient Strong and chemically stable to withstand routine contact without damage. In addition, this type of glass can also be applied to portable electronic products, such as mobile phones (cell phones), tablet computers, and personal media terminals. It also needs to be able to withstand accidental bend...
