THE METHOD FOR PREPARING A METAL ALUMINUM HYDRIDE HAVING THE FORMULA M(ALH4)X WHERE M IS A METAL SELECTED FROM THE GROUP CONSISTING OF ALKALI METALS AND ALKALINE EARTH METALS AND X IS THE VALENCE OF THE SELECTED METAL WHICH COMPRISES HEATING IN A CONFINED REACTION ZONE A MATERIAL SELECTED FROM THE GROUP CONSISTING OF ALKALI METALS, ALKALINE EARTH METALS AND HYDRIDES OF SUCH METALS WITH FINELY DIVIDED ALUMINUM METAL AND A COMPLEX HYDRIDE HAVING THE FORMULA M(ALH4)X WHERE M AND X HAVE THE MEANINGS STATED ABOVE IN AN AMOUNT FROM ABOUT 0.1 TO 25 PERCENT BY WEIGHT BASED UPON THE WEIGHT OF SAID SELECTED MATERIAL USED IN AN INERT LIQUID CARRIER AT A TEMPERATURE ABOVE ABOUT 100*C. BUT BELOW THE DECOMPOSITION TEMPERATURE OF THE METAL ALUMINUM HYDRIDES IN THE PRESENCE OF HYDROGEN UNDER SUPERATMOSPHERIC PRESSURE ABOVE ABOUT 2500 P.S.I. WHILE AGITATING THE MIXTURE UNTIL REACTION BETWEEN SAID SELECTED MATERIAL, ALUMINUM AND HYDROGEN IS COMPLETE.
