More Information
Summary:The present disclosure is directed to methods of preparing substantially spherical metallic alloyed particles, having micron and sub-micron (i.e., nanometer)-scaled dimensions, and the powders so prepared, as well as articles derived from these powders. In particular embodiments, these metallic alloyed particles, complising rare earth metals, can be prepared in sizes as small 80 nm in diameter with size variances as low as 2-5%.
