Abstract: Polishing powders of nanoscale dimensions are disclosed. Complex, multi-metal oxides are disclosed as constituents for chemical mechanical planarization, (CMP) as well as polishes for optical components, photonic devices, and other applications.

Abstract: A method of producing metal and alloy fine powders having purity in excess of 99.9%, preferably 99.999%, more preferably 99.99999%. Fine powders produced are of size preferably less than 10 micron, more preferably less than 1 micron, and most 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 useful in various applications such as biomedical, sensor, electronic, electrical, photonic, thermal, piezo, magnetic, catalytic and electrochemical products.
