Study of the Process of the Formation of Niobium Carbide on Graphite Particles,
Abstract
The procedure and equipment were worked out for gas vapor phase deposition of refractory metal carbides and nitrides onto graphite particles in a fluid bed. Details were worked out specifically for the deposition of niobium carbide. Curves showing deposit thickness as function of process time and temperature indicate a diffusion process. X-ray structural analyses established that a uniform deposit of niobium carbide, of nearly stoichiometric composition, was formed about the entire particle surfaces. (Author)
