溶胶-凝胶法的应用研究

为研究溶胶-凝胶法的应用,文章通过研究溶胶-凝胶法的基本原理、工艺过程的影响因素,总结溶胶-凝胶法的优缺点。结果表明,水的加入量、温度、醇盐的滴加速度、反应液的pH都会影响溶胶-凝胶法的产品质量。溶胶-凝胶法可制得的材料主要有以下几大类型:单晶、纤维材料、涂层和薄膜材料、超细粉末材料及复合材料等,有很大的发展前景。

Studies On ApplicatiOn Of Sol-gel MethOd

The paper studied the mechanism and influence factor of process of sol-gel method and generalized its advantages and disadvantages.Results showed the addition amount of water,the dropping-speed alkoxide,the pH of reaction solution all affected on the product quality of sol-gel method.Sol-gel method could prepare some materials: single crystal,fiber material,coating,film material,superfine powder material.Sol-gel method had good development prospects.
