溶胶凝胶法合成钙长石的研究

STUDY ON THE ANORTHITE SYNTHESIZED BY SOL-GEL METHOD

采用溶胶凝胶法制备钙长石粉末,利用各种测试技术对样品进行了红外、衍射分析以及粒度分析;系统的研究了表面活性剂对细度的影响。研究表明,加入1%的PVA能显著提高颗粒的比表面,降低颗粒的细度。

Anorthite powder synthsized by sol-gel method, is tested by using all kind of instrumentation technology including Infra-red spectroscopy analysis and XRD and particle size analysis. In addition, by studying systematically the effect of surfactant on particle size, we obtain best technical parameters. The results indicated that adding 1% of PVA can evidently improve specific area of powder and lower the particle size.
