Zirconium oxide composite calcium phosphate ceramic slurry and preparation method and application thereof
The invention discloses zirconium oxide composite calcium phosphate ceramic slurry and a preparation method and application thereof. The biological activity of hydroxyapatite and the high strength and good toughness of zirconium oxide are combined, and after aluminum powder is added, a large amount of heat is released through an aluminothermic reaction to sinter a material, magnesium oxide generated at a high temperature and added calcium oxide are used as a stabilizer together, so that the thermal expansion coefficient of the product is reduced, and the prepared slurry is relatively good in flowability. The slurry provided by the invention is matched with an SLA-3D printing procedure, the printed false tooth is similar to a natural tooth, the surface of the sample is smooth and does not crack, and the slurry can be widely popularized and used.
本发明公开了一种氧化锆复合钙磷陶瓷浆料及其制备方法和应用，本发明结合了羟基磷灰石的生物活性和氧化锆的高强度和良好韧性，加入铝粉后通过铝热反应放出大量热量来烧结材料，高温下生成氧化镁和加入的氧化钙共同作稳定剂，减小了产物的热膨胀系数，制得的浆料流动性较好。采用本发明的浆料与SLA‑3D打印程序相匹配，打印出的义齿与天然牙齿类似，样品表面平整不开裂，可广泛推广使用。
