Abstract

Calcium vapor reduction of niobium oxide compounds has been studied at temperatures from 1023 to 1123 K. The adiabatic temperature of calcium reduction of niobium pentoxide (3020 K) and the Mg4Nb2O9 niobate (2525 K) has been determined by thermodynamic modeling with the TERRA software suite. We have assessed the effects of process temperature, reduction time, and precursor powder particle size on the degree of reduction, specific surface area, and pore structure of the niobium powders.
