Collagen dispersions are heterogeneous mixtures of collagen nanofibrils, manufactured from bovine corium, and buffered water. The dispersion is viscous and can support many times its mass in metal dust. After freezing and lyophilizing the dispersions, porous protein-metal structures are recovered. This material is then sintered at temperatures between 600 and 1300 �C. During the sintering process the metal particles diffuse into one another while the collagen scaffold is burned away. The closer the temperature is to the specific metal's melting point the more diffusion that occurs and the stronger the resulting bridge between particles. The oxidation of the particle's surface may pose issues for the bridging between particles and the resulting strength. The void left by the removal of the collagen provides more surface area that is able to be utilized as a catalyst or allow higher rates of extraction of oil and gas from wells if utilized as a proppant. Several metals have been successfully processed with the lost protein technology. Results of this research including required processing and analysis will be presented.
