Preparation method of antibacterial dental restoration nano zirconium oxide powder
The invention relates to a preparation method of antibacterial dental restoration nano zirconium oxide powder, and the method comprises the following steps: (1) adding yttrium oxide and a soluble zinc compound into a zirconium oxychloride solution at 40-60 DEG C to form a zirconium-yttrium-zinc composite solution; (2) putting the composite solution in the step (1) into a reaction kettle, and carrying out hydrolysis reaction to obtain hydrolyzed slurry; (3) rinsing and drying the hydrolyzed slurry in the step (2) to obtain precursor powder; (4) performing high-temperature calcination treatment on the precursor powder in the step (3) to obtain calcined powder; (5) carrying out ball milling and granulation treatment on the calcined powder in the step (4) to obtain the antibacterial nano zirconium oxide powder. Three metal ions of zinc, yttrium and zirconium are hydrolyzed, dried, calcined, ball-milled and granulated to prepare the material which is good in biocompatibility and mechanical property, obvious in bactericidal effect and long in acting time.
本发明涉及一种抗菌型牙科修复纳米氧化锆粉体的制备方法，包括以下步骤，(1)在40℃‑60℃的氧氯化锆溶液中加入氧化钇、可溶性锌化合物，形成锆钇锌复合溶液；(2)将步骤(1)中的复合溶液放入反应釜中进行水解反应，得到水解浆料；(3)将步骤(2)中的水解浆料进行漂洗、烘干得到前驱体粉体；(4)将步骤(3)中的前驱体粉体进行高温煅烧处理，得到煅烧粉；(5)将步骤(4)中的煅烧粉进行球磨、造粒处理，得到抗菌型纳米氧化锆粉体。将锌、钇、锆三种金属离子经过水解、烘干、煅烧、球磨和造粒后制备出具有生物相容性好，力学性好、杀菌效果明显，作用时间长的材料。
