Abstract
The invention provides a kind of glass ceramics, the composition of the glass ceramics is represented by mole percentage, containing: SiO 2 : 48~65%; Al 2 o 3 : 10~20%; Li 2 O: 12-29%; ZnO: 0.1-8%; P 2 o 5 : 0.1~6.5%; ZrO 2 : 0.1~8%, of which Al 2 o 3 / SiO 2 0.18 to 0.38. Through reasonable component design, the glass ceramics obtained by the present invention are suitable for chemical strengthening; meanwhile, the glass ceramics and glass ceramic products obtained by the present invention have excellent mechanical properties, which are suitable for use in display devices or electronic devices.
Description
technical field [0001] The present invention relates to a glass ceramic, in particular to a chemically strengthenable glass ceramic. 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 has excellent chemical stability to withstand routine contact without damage. In addition, this type of glass can also be applied to portable electronic products, such as mobile phones, tablet computers, and personal media terminals. To withstand the accidental bending, scratches and impacts that may occur during use, this puts forward higher requ...
