摘要： PLATE. IN ONE PREFERRED EMBODIMENT, A STEADY STREAM IS SEGMENTALLY CUT BY A VIBRATING WIRE OR SCREEN TO PRODUCE DROPS PRIOR TO CONTACTING THE WATER BATH OR PLATE.

THIS INVENTION COMPRISES METHODS FOR PRODUCING SHAPED ALUMINUM ALLOY PARTICLES. THESE PARTICLES CAN RANGE FROM 1-99 PERCENT ALUMINUM, ALTHOUGH FOR SUBSEQUENT USE AS ACTIVE METAL CATALYSTS, THE CONCENTRATION RANGES FROM 50 TO 90 PERCENT ALUMINUM AND 10 TO 50 PERCENT OF NICKEL, COBALT, COPPER OR IRON. THESE SHAPED PARTICLES ARE PRODUCED BY A MELT DROP TECHNIQUE WHEREBY INDIVIDUAL DROPS OF ALLOY ARE DROPPED INTO A WATER BATH OR ONTO A COLD FLAT
