在分析莱尼斯法缺点的基础上，对钛醇盐合成方法作了改进。利用自制的新鲜钛乙醇盐为原料。研究了醇盐水解法制备高纯、微细、单分散ＴｉＯ＿２粉末的工艺。所得ＴｉＯ＿２微粉理化性质及用其做成的ＰＴＣ电阻器的电性能全部达到有关电子陶瓷厂的技术要求。研究表明，醇盐水解法是一种很有希望和发展前景的新方法，它在超微粉制造工艺中具有潜在优势和实际意义。 Based on the analysis of the defects of Lenis method, the synthesis of titanium alkoxide was improved. Using homemade fresh titanium alkoxide as raw material. The preparation of high purity, fine and monodispersed TiO_2 powders by alkoxide hydrolysis was studied. The physical and chemical properties of the resultant TiO 2 micropowder and the electrical properties of the PTC resistor made of the same all meet the technical requirements of the related electronic ceramic factory. Studies have shown that alkoxide hydrolysis is a promising and promising new method, which has potential advantages and practical significance in the process of manufacturing ultrafine powder.
