Description

Glass ceramics and glass ceramics products
The application is a divisional application of the application patent application with the application number of 202010603489.7 and the application date of 2020, 06 and 29, named as microcrystalline glass and microcrystalline glass products.
Technical Field
The present application relates to a glass ceramic, and more particularly, to a glass ceramic and a glass ceramic product having excellent mechanical properties suitable for use in electronic devices or display devices.
Background
In recent years, with the continuous rise and development of consumer electronics, glass is used as a transparent material with good performance in a large number of such electronic devices. Since electronic devices have many precise electronic components inside, it is necessary to provide a cover plate or a case to protect the electronic components inside. In the prior art, metal is used as a cover plate material, but the metal has the defects of easy oxidation, electromagnetic signal shielding and the like. There are also documents that disclose the use of glass as a cover plate, for example, chinese patent CN101508524a discloses a chemically strengthened glass whose properties such as drop resistance and fracture toughness are hardly satisfactory. As a ceramic material that does not affect a signal, it has a good texture and a high thermal conductivity, but is inferior in workability and high in cost as compared with glass.
The glass ceramics can have physical properties which cannot be obtained in glass by crystallization dispersed in the glass, and have remarkable advantages over general glass in terms of bending resistance, abrasion resistance, and the like due to the formation of crystallites in the glass. Based on the advantages, the microcrystalline glass or the microcrystalline glass product processed by the microcrystalline glass is applied to display equipment or electronic equipment with high requirements on shatter resistance, compression resistance and scratch resistance. Therefore, the development of glass ceramics and glass ceramics products which have excellent mechanical properties and are suitable for display equipment or electronic equipment with high requirements on shatter resistance, compression resistance and scratch resistance is a target pursued by technological staff.

If SiO is 2 The content is more than 65 percent, the glass smelting difficulty is increased, and the forming of the glass is not facilitated, thus SiO 2 The upper limit of the content is 65%, preferably 60%.

Thus Li 2 The lower limit of the O content is 5%, preferably 6%, more preferably 7%. If too much Li is contained 2 When O is used for crystallization of glass, crystals tend to be large, and haze of glass ceramics and glass ceramics products increases, and light transmittance decreases. Thus Li 2 The upper limit of the O content is 15%, preferably 12%, more preferably 10%. In some embodiments, about 5%, 5.5%, 6%, 6.5%, 7%, 7.5%, 8.0%, 8.5%, 9%, 9.5%, 10%, 10.5%, 11%, and may be included,11.5%, 12%, 12.5%, 13%, 13.5%, 14%, 14.5%, 15% Li 2 O。

On the other hand, if ZnO is contained excessively, the coefficient of thermal expansion of the crystallized or chemically strengthened glass ceramic or glass ceramic product becomes large, which is disadvantageous for subsequent further processing. Therefore, the upper limit of the ZnO content is preferably 10%, more preferably 8%, and still more preferably 6%. In some embodiments, about 0.5%, 1%, 1.5%, 2%, 2.5%, 3%, 3.5%, 4%, 4.5%, 5%, 5.5%, 6%, 6.5%, 7%, 7.5%, 8%, 8.5%, 9%, 9.5%, 10% ZnO may be included.

Thus, znO/Li is preferred in the present invention 2 O is 0.1 to 1.8, more preferably ZnO/Li 2 O is 0.2 to 1.5, and ZnO/Li is more preferable 2 O is 0.3-1.0.
