Preparation of Hafnium Carbide by Dynamic Compaction of Combustion Synthesized Materials

Abstract

Solid hafnium carbide has been produced by explosive compaction of Self-Propagating High-Temperature Synthesis (SHS) produced material. The experimental technique is described and various parameters that affect the dynamic compaction are discussed. Densities greater than 90 percent theoretical were attained but some samples exhibited poor interparticle bonding and cracking. It is concluded that the amount of heat given off by the SHS reaction is insufficient to both propagate the synthesis process and properly sinter the SHS product. Keywords: Ceramic materials.
