Conditions for the formation of niobium carbide by the reduction of riobium pentoxide with soot in a hydrogen atmosphere and in a vacuum were investigated. The optimal conditions for obtaining niobium carbide were: heating a charge containing 97% of the calculated quantity of soot at 1700 un. Concent 85% C for one hour; and heating a stoichiometric charge twice at 1700 un. Concent 85% C in vacuum for one hour with intermediate grinding and screen-sizing of the product. The maximum bound carbon content in the resulting carbide samples corresponds to the formula NbC/sub 0.98/. (P.C.H.)
