APPLICATION OF SUPERCRITICAL TECHNIOUE IN PREPARATION OF ULTRAFINE OXIDE PARTICLE

Institute of Coal Chemistry, Chinese Academy of Sciences, Taiyuan 030001

Received Date: 5 August 1991

Ultrafine particle (UFP)alumina has been prepared by supereritical fluid drying process of inorganic salt with organic solvent system, which is reported for the first time. UFP-alumina prepared from this system is featured by its hish specific surface area, large pore volume, small perticle size and low bulk density.
