摘　　要：采用凝胶法制备纳米氧化锆,先以酒石酸铵络合锆离子,再加入氨水使之与络合物充分混合,之后加入双氧水解除络合,生成氢氧化锆凝胶,待凝胶干燥后,高温下煅烧,再将煅烧后的产品和研磨助剂一起研磨,最终得到粒径为80nm的类球形的纳米氧化锆。Zirconium hydroxide precursor were synthesized by a gel process using ZrOCl2 8H2O and ammonia as raw material, ammonium tartrate as complexant, H2O2 releasing the complex. Dry precursor was calcined in high temperature. The product was ground in an agate mortar with dispersant and grlndmg aid, getting nano-sized ZrO2 powders in around 80 nm.
