Abstract
Provided in the present invention is a rare earth-doped reinforced glass-ceramic, and a preparation method and a use therefor. Raw materials rare earth-doped reinforced glass-ceramic comprise at least one of the following rare earth oxides: TaO, LaO, YO, TmO, or NbO. In the present invention, a glass article doped with at least one rare earth oxide from among TaO, LaO, YO, TmO, or NbOis subjected to thermal treatment and ion exchange to produce the rare-earth doped reinforced glass-ceramic. In the rare earth-doped reinforced glass-ceramic, due to the high field strength and high accumulation effects of the rear earth element, the crystal size of the glass-ceramic is caused to low, and the crystal ratio thereof to be high, thus being able to effectively improve the mechanical performance and visible light transmittance of the glass-ceramic, and effectively controlling uniform devitrification of the glass. The invention is suitable for use in cover panels of electronic devices.
