A process 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.degree. C. to about 1400.degree. C. for about 1 minute to about 96 hours to produce the desired ceramic or metal powder.

Process for preparing submicron/nanosize ceramic powders from precursors

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.degree. C. to about 1400.degree. C. for about 1 minute to about 96 hours to produce the desired ceramic or metal powder.

A porous matrix of lithium aluminate particles for molten alkali metal carbonates electrolytes having about 5 to about 50 volume percent, based upon the volume of the solids, of electrically non-conductive, active electrolyte compatible fibers having an average diameter of about 1 to about 50 microns and an average length greater than about 5 times the average diameter. Such matrices reduce matrix cracking upon loading with molten carbonates active electrolyte and provide high surface area over long term fuel cell operation.

Molten carbonate fuel cell electrolyte toughening

A process 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.degree. C. to about 1200.degree. C. for about 1/2 to about 8 hours to produce the desired ceramic or metal powder.

A molten alkali metal carbonates fuel cell porous anode of lithium ferrite and a metal or metal alloy of nickel, cobalt, nickel/iron, cobalt/iron, nickel/iron/aluminum, cobalt/iron/aluminum and mixtures thereof wherein the total iron content including ferrite and iron of the composite is about 25 to about 80 percent, based upon the total anode, provided aluminum when present is less than about 5 weight percent of the anode. A process for production of the lithium ferrite containing anode by slipcasting.
