Hydroxyapatite-based composite ceramic material and preparation method thereof
The invention discloses a hydroxyapatite-based composite ceramic material and a preparation method thereof, and particularly relates to the technical field of ceramics, the hydroxyapatite-based composite ceramic material comprises hydroxyapatite-based ceramic powder, the preparation method of the hydroxyapatite-based ceramic powder comprises the following steps: step 1, mixing hydroxyapatite (HA) and A203 raw materials to prepare a mixture; 2, the mixture in the step 1 is put into a sand mill to be subjected to sand milling; and step 3, drying the sanded mixture. According to the invention, the ceramic can be sintered at 1200-1250 DEG C without adding a binder and using buried sintering powder, the ceramic has the advantages of high strength, no sticky powder, uniform pore dispersion and no buried sintering powder, the buried sintering powder can be prevented from falling and being inhaled into the lung, the safety of the device is improved, the thermal expansion coefficient of the ceramic can be adjusted, and the service life of the device is prolonged. Good biocompatibility is improved, and rejection is avoided.
本发明公开了一种羟基磷灰石基复合陶瓷材料及其制备方法，具体涉及陶瓷技术领域，包括：羟基磷灰石基陶瓷粉体，所述羟基磷灰石基陶瓷粉体的制备方法如下：步骤一，将羟基磷灰石(HA)和A203原材料进行混合，制得混合物；步骤二，将步骤一中的混合物投入砂磨机中进行进行砂磨；步骤三，将砂磨后的混合物进行干燥。本发明可以在不添加粘结剂、不用埋烧粉的情况下在1200～1250℃烧结成瓷，陶瓷具有很高的强度，无粘粉、孔隙分散均匀，且不含埋烧粉，可以避免埋烧粉掉落吸入肺部，提升装置的安全性，并可以对陶瓷的热膨胀系数进行调节，提升具有具有很好的生物相容性，避免排斥。
