摘　　要：采用溶胶凝胶法制备了超细氧化锡粉末，并研究了粉末的特性．实验结果表明：适宜的制备条件是，以四氯化锡为原料，进行水解反应的酸度ｐＨ２～５，保持酸度恒定，控制反应的温度２５～７０℃，在反应底液中加入筛选的分散剂，反应过程中剧烈搅拌，能够获得超细氧化锡粉末．对产品进行了Ｘ射线衍射、红外光谱分析和比表面积测定等．这一制备技术具有设备与流程简单，操作条件容易控制，产品粒度细（００２５μｍ），纯度高（＞９９９％），比表面积大（３２ｍ２／ｇ），性能好等特点．The ultrafine SnO 2 powder was prepared by the sol gel method. And the properties of the product were studied. The experimental results show that the appropriate preparing conditions are as follows: using tin tetrachloride as original material, hydrolysis acidity pH 2～5, containing constant acidity, controlling reaction temperature 25～70 ℃, adding selected disperser to reaction base solution. When vigorously stirred, ultrafine SnO 2 can be obtained. Some characteristic properties of the product were determined by X ray diffraction, ultrared spectral and BET method and so on. The preparing technique has many advantages: simple equipment and flowsheet, easy controlling operation conditions, fine powder of uniform size(0 025 μm), high purity(>99 9%), large specific surface area(32 m 2/g), and good properties of the product.
