Zirconium carbide (ZrCx) ceramics with different carbon contents were fabricated by reaction hot pressing. Nominal stoichiometry ranged from x = 0.6 to x = 0.98 with 0.05 intervals. The final ceramics were characterized to determine relative densities using Archimedes method, carbon content employing thermal gravimetric analysis, oxygen content using inert gas-fusion, and microstructure by scanning electron microscopy. The phases in each ceramic were determined by x-ray diffraction, selected area electron diffraction, and neutron powder diffraction. The effects of the carbon content and heat treatment on carbon vacancy ordering were determined.
