ABSTRACT:
A method for the manufacture of ultrafine particles or atom clusters is disclosed. The ultrafine particles of size between about 10 to 1000 Angstroms are formed by the disruption of the crystal lattice or micrograin structure of the metal, alloy or intermetallic compound in one or both of two spaced electrodes by a high frequency, high voltage, high peak current discharge. The ultrafine particles are not subjected to fractionation as in evaporative processes and accordingly are remarkably predictable in both particle size, distribution of sizes and atomic composition, and also are readily transportable in carrier gases.
