Finely divided metal and alloy powders can be prepared by reduction or co‐reduction of metal salts in organic solvents. By means of this novel “cold powder technology”, microcrystalline to amorphous metals and alloys are obtained (particle size according to SEM photographs 10–100 nm) which can also be generated on support materials. This is of interest for catalytic applications.
