Process for preparing submicron/nanosize ceramic powders from precursors incorporated within a polymeric foam

摘要

A for preparing uniform, agglomerate free, submicron/nanosize ceramic powders from a polymeric foam comprising metal cations homogeneously incorporated within a foam cell structure of the polymeric foam. The polymeric foam is heated to remove any solvent, and calcined at a temperature of about 400 DEG C. to about 1400 DEG C. for about 1 minute to about 96 hours to produce the desired ceramic or metal powder.
