摘要: 探讨了在有机分散剂存在下，采用氨水中和水解TiCl₄制备高纯TiO₂的工艺方法。研究了分散剂种类和用量，反应物浓度，加料方式,熟化温度和时间对TiO₂性能的影响。制取了纯度≥99.5％，粒径<1.0μ，近似球形的TiO₂微粉。100kg级的试验结果表明，TiO₂微粉的理化指标和制成的PTC电子元件的电性能均接近日本TDK公司同类产品的技术指标。

Abstract: The process for preparation of high purity ultrafine TiO₂ powder by means of neutralization of hydrolyzed TiCl₄ solution with ammonia in the presence of organic dispersant was developed. The effects of the dispersant type and its consumption, concentration of reactants, feeding mode,maturing temperature and time on the properties of TiO₂ were investigated.The spheroidal TiO₂ powder was prepared whose purity is over 99.5%,particle diameter is less than 1.0μ,The results of 100kg grade test show the physicochemical properties of the ultrafine TiO₂ powder and the characteristics of PTC electronic component made from the TiO₂ powder approach the technical index of similar products of TDK Co. in Japan.
