Abstract
A method for producing an alloy in atomized form, wherein the alloy includes between about 10% to about 100% of a silicon based alloy, including obtaining a base silicon-iron alloy mixture and an atomization unit having an atomization chamber and a plurality of nozzles, injecting an atomizing fluid into the atomization chamber via the plurality of nozzles, introducing the base silicon-iron alloy mixture into the atomization chamber such that the atomizing fluid impinges on the base silicon-iron alloy mixture to produce the alloy in atomized form, cooling the alloy in atomized form using a pool of water so as to produce a cooled alloy product, retrieving the cooled alloy product and drying the cooled alloy product to produce the alloy in atomized form.
