An investigation of process variables demonstrated that resistive heating was enhanced by increased plunger length, a reduced plunger shank diameter, and a decreased die wall thickness. Conductive ceramics TiB2, ceramic-metal mixtures Ti plus TiB2, layered composites TiTiB2, and metallized nonconducting ceramics Ti on B4C powder were resistance sintered. Densities approaching theoretical were achieved in times of the order of five minutes without the need for a protective atmosphere. Author
