ABSTRACT:
An apparatus for the production of high density, monolithic ceramic maters. A mixed powder, such as Titanium-Boron is first subjected to uniaxial pressure to form a green compact. The compact is positioned in a vented mold between two steel plates and subjected to Self-Propagation High Temperature Synthesis to form a molten ceramic, and then to an explosively generated shockwave by an explosive charge positioned on the upper steel plate so as to compress the molten ceramic between the two plates to form high purity ceramic of more than 90% theoretical density.
