一种高强度齿科修复用陶瓷复合材料及其制备方法
摘要：
本发明公开了一种高强度齿科修复用陶瓷复合材料，其原料组成为：SiO231～41wt％、Li2CO325～31wt％、Al2O32～5wt％、K2CO32～4wt％、(NH4)2·HPO42～8wt％、ZrSiO47～17wt％、Y2O30.5～2wt％、MgO 1～2wt％，以及着色剂CeO20.2～1wt％、TiO20.2～1wt％；所述材料为含氧化锆、二硅酸锂和残留玻璃相三种物相的陶瓷复合材料。此外，还公开了上述高强度齿科修复用陶瓷复合材料的制备方法。本发明陶瓷复合材料不仅具有高的强度和稳定性，而且具有与天然牙齿类似的色度及良好的光学透过率，有利于实现实际应用，适用于义齿移植、骨科修复及其他对陶瓷强度有特殊要求的领域。
摘要（英）：

The invention discloses a high-strength dental repair ceramic composite material, which comprises the following raw materials in percentage by weight:31-41 percent of SiO2,25-31 percent of Li2CO3,2-5percent of Al2O3,2-4 percent of K2CO3,2-8 percent of (NH4) 2.HPO4,7-17 percent of ZrSiO2, 0.5-2 percent of Y2O3,1-2 percent of MgO, 0.2-1 percent of a colorant CeO2 and 0.2-1 percent of TiO2, whereinthe material is a ceramic composite material containing three phases of zirconia, lithium disilicate and residual glass.In addition, the invention also discloses a preparation method of the high-strength dental repair ceramic composite material.The ceramic composite material not only has high strength and stability, but also has chromaticity similar to natural teeth and good optical transmittance,is favorable for realizing practical application, and is suitable for the fields of denture transplantation, orthopaedic repair and other special requirements on ceramic strength.
