Composite ceramic material containing CaSO4 and beta-TCP and preparation method and application of composite ceramic material
The invention discloses a composite ceramic material containing CaSO4 and beta TCP and a preparation method and application thereof. The material is composed of beta TCP ceramic and CaSO4.2H2O in a mass ratio of 1: 5-11, and the mass ratio of beta tricalcium phosphate to hydroxyapatite in the beta-TCP ceramic is 7: 3. The method comprises the following steps: grinding and sieving aluminum sulfateoctadecahydrate powder, mixing the materials with calcium sulfate dihydrate powder, putting the mixture into a pressure cooker, performing heating, performing pressurizing, maintaining the pressure, performing drying to obtain alpha calcium sulfate hemihydrate, and sufficiently and uniformly mixing the calcium sulfate dihydrate powder with a doping material to obtain composite ceramic material powder consisting of CaSO4.2H2O and beta-TCP ceramic. The application comprises the following steps: preparing the porous calcium sulfate/beta-TCP biological scaffold from the powder of the composite ceramic material; a biological scaffold is implanted into a human body. The bone repair material prepared by the invention has good biocompatibility and biodegradability, and has good application prospects in the fields of local administration, dental restoration and the like.
本发明公开一种含有CaSO4和β‑TCP的复合陶瓷材料及制备方法和用途，材料由β‑TCP陶瓷与CaSO4·2H2O的质量比为1:5～11组成，其中β‑TCP陶瓷中β‑磷酸三钙与羟基磷灰石的质量比为7:3。方法包括将十八水化硫酸铝粉体研磨过筛与二水硫酸钙粉体混合、放于高压锅内加温加压保压然后干燥后得α‑半水硫酸钙、将二水硫酸钙粉体与掺杂料充分混合均匀得由CaSO4·2H2O和β‑TCP陶瓷组成的复合陶瓷材料粉料。用途包括将复合陶瓷材料的粉料制成多孔硫酸钙/β‑TCP生物支架；将生物支架植入人体。本发明制备出的骨修复材料具有良好的生物相容性、生物可降解性，在局部给药、牙齿修复等领域具有良好的应用前景。
