Si3N4/CPP composite ceramic material and preparation method and application thereof
The invention belongs to the technical field of biological ceramic materials, and particularly relates to a calcium polyphosphate/silicon nitride composite ceramic material and a preparation method and application thereof. The method comprises the following steps: preparing CPP suspension liquid and Si3N4 suspension liquid, adding the Si3N4 suspension liquid into the CPP suspension liquid, uniformly stirring, filtering, pressing and sintering to obtain the Si3N4/CPP composite ceramic material. The composite ceramic material has excellent mechanical properties and biological activity, not only can effectively improve the degradation rate of calcium polyphosphate, but also can increase the compressive strength, is good in biocompatibility, and has a wide application prospect as a bone repair material.
本发明属于生物陶瓷材料技术领域，具体涉及一种聚磷酸钙/氮化硅复合陶瓷材料及其制备方法与应用。所述方法为：先制备CPP悬浮液和Si3N4悬浮液，将Si3N4悬浮液加入到CPP悬浮液中，搅拌均匀后，经过过滤、压制烧结获得Si3N4/CPP复合陶瓷材料。该复合陶瓷材料具备优异的力学性能和生物活性，不仅能够有效改善聚磷酸钙的降解速率，同时还能够增加抗压强度，而且生物相容性好，该复合材料作为骨修复材料具有广阔应用前景。
