    Abstract: Disclosed herein are systems and methods for synthesis of spheroidized metal or metal alloy powders using microwave plasma processing. In some embodiments, the metal or metal alloy may comprise a highly ductile, soft, and/or malleable metal or metal alloy such that machining of the metal or metal alloy is difficult or impossible. In some embodiments, a volatile material is dispersed within the metal or metal alloy feedstock to enable machining and pre-processing of the feedstock. In some embodiments, the dispersed volatile material alters the physical properties of the feedstock, such that the metal or metal alloy, which is difficult to machine due to high ductility, softness, and/or malleability, is easily machined in a pre-processing step. In some embodiments, the pre-processed feedstock, can be fed into a plasma processing apparatus. In some embodiments, the volatile material dispersed within the feedstock material may be vaporized upon exposure to the microwave plasma apparatus. In some embodiments, plasma processing of the pre-processed feedstock material may synthesize pure, spheroidized metal or metal alloy particles, with substantially no contamination of the volatile material ion the final product.

    Abstract: Disclosed herein are embodiments of methods, devices, and assemblies for processing feedstock materials using microwave plasma processing. Specifically, the feedstock materials disclosed herein pertains to scrap materials, dehydrogenated or non-hydrogenated feed material, recycled used powder, and gas atomized powders. Microwave plasma processing can be used to spheroidize and remove contaminants. Advantageously, microwave plasma processed feedstock can be used in various applications such as additive manufacturing or powdered metallurgy (PM) applications that require high powder flowability.
