Abstract

Particles consisting of metal carbides, borides, silicides or nitrides are dispersed in an ammoniated solution containing a soluble compound of Os, Rh, Ru, Ir, Au, Pt, Pd, Ag, As, Cu, Sn, Ni or Co, and the solution reacted with a reducing gas at a temperature above 200 DEG F. to precipitate metal from the solution on to the particles. Carbides, borides, silicides and nitrides specified are those of Ti, Zr, Hf, Ta, V, Nb, Cr, Mo, W and Si. The ammoniated solution may be organic or inorganic, and acid, basic or neutral; and the anion of the coating metal may be the sulphate, chloride, carbonate, hydroxide, fluosilicate or acetate. If necessary, e.g. when coating with Ni or Co, a hydrogenation catalyst such as ferrous sulphate or a mixture of sodium sulphide and potassium cyanide, is added to the solution. Reducing gases mentioned are hydrogen, carbon monoxide, methane, producer gas and natural gas. The coated particles may be compacted into desired shapes as by rolling or pressing with or without preliminary sintering and intermediate annealing steps. Specification 824,091 is referred to.
