ABSTRACT:
A method for atomizing high temperature melts to achieve greater efficiency and smaller particle size is described. The method involves the employment of lower pressure gas coupled with an atomization nozzle larger than prior art structures. The atomization nozzle is part of a close coupled atomization structure having shallow depth dimension. The method allows atomization at melts with reduced likelihood of freeze off. The method reduces heat extraction from the melt while the melt is still contained in the atomization nozzle.
