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, and recycled used powder. 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.

Abstract: The embodiments disclosed herein are directed to systems, methods, and devices for producing materials having desired characteristics using microwave plasma. In some embodiments, performing an iterative process may be used to produce a material having desired characteristics, the process comprising forming a microwave plasma within the reaction chamber, analyzing the plasma to determine if properties of the plasma are within a range expected to produce the desired characteristics of the material; and adjusting, based on the analysis of the plasma, one or more parameters. In some embodiments, an extension tube is provided within a microwave plasma apparatus to extend the length of a microwave plasma.

Abstract: The embodiments disclosed herein are directed to systems, methods, and devices for processing a material using a microwave plasma apparatus with an interior liner. In some embodiments, the liner comprises a reduction resistant material layer in direct contact with a hydrogen-containing plasma of a plasma processing apparatus. In some embodiments, the liner may comprise a sleeve disposed between a plasma and one or more concentric tubes of a plasma processing apparatus. In some embodiments, the liner may comprise a coating of material applied to the one or more concentric tubes. In some embodiments, the liner may comprise a flexible ceramic material, such as a ceramic ribbon that is coiled or wrapped in a helix shape spiraling around the interior of the one or more concentric tubes.
