Description

ABSTRACT:
A process is comprised of continuously producing a fine ceramic powder by drying at supercritical conditions. The feed is a sol of ceramic oxides or hydrous oxides which is continuously pressurized and heated to in excess of the critical temperature and pressure of the sol solvent. The solvent transforms to a gas and separates from the fine particulate ceramic oxide powder, which remains in a highly divided state.
