Moorhead, A J; Bomar, E S; Becher, P F

A process for manufacturing large, fully dense, high purity TiB/sub 2/ articles by pressing powders with a sintering aid at relatively low temperatures to reduce grain growth. The process requires stringent temperature and pressure applications in the hot-pressing step to ensure maximum removal of sintering aid and to avoid damage to the fabricated article or the die.
