Abstract
A method of producing high purity nanoscale powders in which the purity of powders produced by the method exceeds 99.99%. Fine powders produced are of size preferably less than 1 micron, and more preferably less than 100 nanometers. Methods for producing such powders in high volume, low-cost, and reproducible quality are also outlined. The fine powders are envisioned to be useful in various applications such as biomedical, sensor, electronic, electrical, photonic, thermal, piezo, magnetic, catalytic and electrochemical products.
