Abstract
This invention relates to a method for controlling exothermic reactions between metal chlorides of Zn, V, Cr, Co, Sn, Ag, Ta, Ni, Fe, Nb Cu, Pt, W, Pd, and Mo, and Al and the use of the method for preparation of metallic alloys and compounds based on base metals Zn, V, Cr, Co, Sn, Ag, Ta, Ni, Fe, Nb Cu, Pt, W, Pd, and Mo. The method provides for a mixture of precursor chemicals including at least one solid base metal chloride to be mixed and reacted exothermically with a control powder based on Zn, V, Cr, Co, Sn, Ag, Ta, Ni, Fe, Nb Cu, Pt, W, Pd, and Mo and then reacting the resulting intermediates with an Al scavenger. Reduction is carried out in a controlled manner to regulate reaction rates and prevent excessive rise in the temperature of the reactants and the reaction products.
