Abstract
A process is described for the hydrided of halogen-substituted compounds of the second to fourth period of Groups III to V of the periodic system, with the exception of gallium, aluminum, carbon, or nitrogen. A finely-granulated aluminum is added to a molten salt melt that consists of 50-67 molar % AlCl.sub.3 (anhydrous) and 50 to 33 molar % of sodium chloride. Then to the stirred, or by some other means dispersed suspension, hydrogen is introduced to hydrided the finely-dispersed aluminum. Thereafter the mixture is reacted with the halogen-substituted compound and the resulting hydrided compound is renewed.
