Flame initiated (800°C, 10 s) or bulk thermal (2 days, 1000°C) reactions of mixed powders of transition metal halides and CaC
produce transition metal carbides (TiC, ZrC, HfC, V
, NbC, TaC, Cr
C and WC) in good yields. The carbides were characterised by X-ray powder diffraction, SEM/EDX, FTIR, microelemental analysis, TEM, electron diffraction and ELNES.
