Unsupported niobium carbide powders of NbC were prepared by carburization of commercial niobium pentoxide in flowing CH 4 -H 2 mixtures. Several routes of synthesis were investigated, leading to final carbides with specific surface areas ranging from 10 to 50 m 2 g Ψ1 . During direct carburization,
