Rapid sintering of ultra-high temperature ceramics (UHTCs) and synthesis of low work-function electron emitting materials have been performed by ultra-fast high temperature sintering technique (UHS). Sintering of UHTCs is a difficult process, due to their high melting temperature, presence of covalent bond, and slower diffusion coefficient.

The microstructure of full dense hot pressed ultra-high-temperature ceramics, namely ZrB 2 , HfB 2 , HfC, and TaC doped with 15 vol% of TaSi 2 , was characterized by x-ray diffraction, scanning and transmission electron microscopy. Concerning the borides, the presence of carbides and oxide of the transition metals was observed well dispersed along the ...
