Preparation method of yttrium oxide stabilized zirconium oxide powder
The invention discloses a preparation method of yttrium oxide stabilized zirconium oxide powder. The invention relates to a preparation method of yttrium oxide stabilized zirconium oxide powder, which comprises the following steps: S1, dissolving zirconium source inorganic salt in water, and then adding yttrium source inorganic salt to obtain a clear water solution containing zirconium and yttrium ions; s2, dissolving a complexing agent in a mixed solution of water and ethanol, then adding into the clear aqueous solution, and uniformly mixing to obtain a colloidal aqueous solution; s3, adding the aqueous solution of the dispersing agent into the sol-like aqueous solution, and stirring until the solution is clear; s4, dropwise adding an alkaline precipitant solution into the solution until zirconium and yttrium ions are completely precipitated, standing, aging, filtering, washing and carrying out vacuum freeze drying to obtain dry powder; s5, roasting the dry powder, and cooling to room temperature to obtain a target product. According to the preparation method provided by the invention, the particle shape and size of the yttrium oxide stabilized zirconium oxide can be more easily controlled, and the method is simple to operate, easily available in raw materials and beneficial to industrial production.
本发明公开了一种氧化钇稳定化氧化锆粉体的制备方法。一种氧化钇稳定化氧化锆粉体的制备方法，包括如下步骤：S1、将锆源无机盐溶解在水中，然后加入钇源无机盐，获得含锆和钇离子的澄清水溶液；S2、取络合剂溶解在水和乙醇的混合溶液中，再加入澄清水溶液中，混合均匀获得胶状水溶液；S3、将分散剂的水溶液加入溶胶状水溶液中，搅拌至溶液澄清；S4、将碱性沉淀剂溶液滴入溶液中，直至锆钇离子完全沉淀后，再静止陈化，过滤、洗涤并真空冷冻干燥获得干燥粉；S5、将干燥粉进行焙烧，冷却至室温，获得目标产物。本发明提出的制备方法可以更容易地控制氧化钇稳定化氧化锆的颗粒形状及尺寸，且此方法操作简单、原料易得、利于工业化生产。
