Abstract
A survey is presented of published work on the hot pressing of metallic carbides. On the basis of a comparison of the apparatus described in the literature, hot-pressing equipment has been built, designed for vacuum sintering using resistance heating, a combination that has many advantages.
Nine metallic carbides from Groups IV, V, and VI of the Periodic Table were hot pressed to high densities, as well as mixed carbides and carbides of varying carbon content. Compacting details are summarized, together with data covering lattice parameters and microhardness.
The purity of the metallic carbides has great significance as regards the sintering mechanism. This is demonstrated both by theory and experiment.
