ABSTRACT:
Solid, homogenous or porous, shaped bodies are formed from different powders such as metals and ceramics by preparation of an aqueous slurry of the powder, which slurry comprises a protein substance which is soluble in water at ambient temperatures and capable of forming an irreversible gel on heating to a temperature not exceeding 90.degree. C. The protein substance, for example albumin, is used in an amount sufficient for the formation of a gel. The slurry is formed into a body of the desired shape by methods such as molding, tapecasting or dropforming and heating to a temperature at least corresponding to the gelling temperature of the protein.
