All-ceramic glass ceramic repair material and preparation method thereof

The invention discloses an all-ceramic glass ceramic repair material which comprises the following raw material components in percentage by mass: 5-8% of ZrO2, 60-75% of SiO2, 26-30% of Li2O, 0.2-0.6%of a complex rare earth element and 0.1-3% of a compound stabilizer. According to the all-ceramic glass ceramic repair material disclosed by the invention, the lithium silicate glass ceramic is takenas a glass matrix, and an appropriate amount of zirconium dioxide is added, so that the mechanical property of the lithium silicate glass ceramic is improved. Meanwhile, due to the addition of the complex rare earth element and the compound stabilizer, the surface microenvironment of the repair material is improved, and the yellowing resistance of the repair material is effectively improved. Moreover, due to the addition of the appropriate amount of the complex rare earth element, the usage amount of the zirconium dioxide is reduced, and excellent mechanical property of the material is maintained. 本发明公开了种全瓷玻璃陶瓷修复材料，其按
