Abstract

A process for decomposing a gaseous thermally unstable metal compound comprises passing the compound through a charge of heated particles in a reactor which is rotated about a horizontal, or slightly inclined, axis so causing the charge to tumble gently while the compound is decomposed to deposit the metal on the particles. The compound may be a carbonyl of Ni, Fe, Co, Cr, Mo or W, the nitroxyl carbonyl of Co, the hydrides of Sn or Sb or the iodide of Be or Ni. More than one metal compound may be used to give an alloy coating. The particles on to which the metal is deposited may be metallic or non-metallic and may be, for example, the same metal as is being deposited, a different one, metal carbides, Al2O3, MgO, Ti2O3, Zr2O3 or ThO2. The meta coated ceramic, refractory or other non-metallic particles may then be heat-treated for diffusion, annealing or dispersion hardening. Ceramic particles so coated may be pressed sintered or heat treated to form cermet materials and dispersion hardened alloys. The decomposition temperature should be above 350 DEG F., preferably above 400 DEG F., and the particles are preferably preheated to a temperature not above 550 DEG F. Ammonia may be added with carbonyl vapours to inhibit carbon formation. The rotation speed should generally be less than 3 r.p.m. A valve means is used on the gas inlet so that the gas only enters through the particles (see Division F2).
