摘　　要：以无机盐TiCl4为前躯体,采用溶胶 凝胶法结合超临界干燥技术制备超细TiO2气凝胶,并采用XRD和TEM技术进行表征。结果表明,采用该法,可制得流动性好的白色球形α TiO2气凝胶颗粒,其平均粒径约为20nm。TiO2 aerogel is prepared by solgel heat and supercritical fluid drying methods with cheap inorganic salts as the raw materialThe ultra fine powders are characterized by means of of XRD and TEM techniques. The result shows that this method can yield white,welldispersioned αTiO2 aerogel
