摘要
采用溶胶 凝胶法结合CO2 超临界流体干燥技术制备了平均粒径为 8nmTiO2 粉体颗粒 ,并采用BET、TEM、SEM、XRD、及DTA TG技术对制得的粉体进行了表征。结果显示出CO2
Titania ulterfine powders with the diameter of 8?nm were prepared by sol gel and supercritical fluid drying methods of CO 2 and characterized by means of BET,SEM,XRD,and TG DTA techniques It was shown that SCFD of carbon dioxide had advantages in the preparation of nanometric particles of oxides with large pore volumes and high specific surface areas
