Abstract: HIGHLY DISPERSED ALLOY MATERIALS OF NICKEL AND MOLYBDENUM AND/OR TUNGSTEN HAVING A VERY HIGH SURFACE AREA ARE MADE BY THE CONTROLLED REDUCTION OF A MXTURE OF COMPOUNDS OF THE METALS IN A REDUCING ATMOSPHERE. THESE ALLOYS AND THEIR SULFIDES ARE USEFUL IN CATALYSIS SUCH AS HYDROCRACKING, HYDROGENATION-DEHYDROGENATION AND HYDROISOMERIZATION.
