Aluminum oxide and germanium oxide co-doped zirconium oxide composite material and preparation method thereof
The invention relates to the technical field of zirconium oxide composite materials, in particular to an aluminum oxide and germanium oxide co-doped zirconium oxide composite material and the preparation method thereof, wherein the composite material is obtained by doping germanium oxide and aluminum oxide into zirconium oxide, mixing, and sequentially carrying out wet ball milling, granulation, dry pressing, cold isostatic pressing and sintering. The aluminum oxide and germanium oxide co-doped zirconithe composite material has the advantages that the excellent low-temperature aging resistance of germanium oxide is combined, and the aluminum oxide and germanium oxide co-doped zirconithe ceramic material is adopted to break through the condition that the mechanical property of the existing tetravalent oxide is relatively low; therefore, the low-temperature aging resistance of the germanium oxide stabilized zirconithe ceramic material is improved, the mechanical property of the material is also improved, and the clinical service life of the zirconithe ceramic material is prolonged.
本发明涉及氧化锆复合材料技术领域，是一种氧化铝氧化锗共掺杂氧化锆复合材料及其制备方法，前者是向氧化锆中掺杂氧化锗和氧化铝混合后，依次经过湿法球磨、造粒、干压成型、冷等静压和烧结后得到。本发明氧化铝氧化锗共掺杂氧化锆复合材料的优势在于：结合了氧化锗优异的抗低温时效性能，采用氧化铝氧化锗共掺杂氧化锆陶瓷材料以突破现有四价氧化物机械性能较低的情况，不仅提高了氧化锗稳定氧化锆陶瓷材料的抗低温时效性能，还改善了材料的机械性能，有利于延长氧化锆陶瓷材料的临床使用年限。
