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.

Process for producing spheroidized powder from feedstock materials

The present technology is directed to a system for controlling the electron energy distribution function in an atmospheric and near-atmospheric low-temperature plasma by subjecting the generated plasma to a repetitive nanosecond-pulsed voltage that is completely decoupled from the means that generated the plasma (i.e., decoupled from an electron-beam). The repetitive nanosecond-pulsed voltage generates a nanosecond-pulsed electric field that affects the energy of the electrons in the plasma without affecting the energy of the ions.

Decoupled tunable plasma system for the dissociation of molecular fluids

Methodologies, systems, and devices are provided for producing metal spheroidal powder products. By utilizing a microwave plasma, control over spheriodization and resulting microstructure can be tailored to meet desired demands.

Spheroidal titanium metallic powders with custom microstructures

Disclosed herein are devices, systems and methods of use of an improved liner for a plasma torch. In particular, a segmented liner for use in a plasma torch (e.g., annular torch, swirl torch) is provided. In general, the improved segmented liner has improved thermal shock resistance capabilities over conventional unitary liners.

Segmented liner and methods of use within a microwave plasma apparatus

Methodologies, systems, and devices are provided for producing metal spheroidal powder products. Dehydrogenated and spheroidized particles are prepared using a process including introducing a metal hydride feed material into a plasma torch. The metal hydride feed material is melted within a plasma in order to dehydrogenate and spheroidize the materials, forming dehydrogenated and spheroidized particles. The dehydrogenated and spheroidized particles are then exposed to an inert gas and cooled in order to solidify the particles into dehydrogenated and spheroidized particles. The particles are cooled within a chamber having an inert gas.

Spheroidal dehydrogenated metals and metal alloy particles

Methods are disclosed for producing core-shell particles having a uniform size using a microwave plasma process. More particularly, methods of the present technology are used to manufacture core-shell particles having a core at least partially surrounded by a shell. The core and shell of the core-shell particles are chemically distinct. Methods of the present technology occur within a plasma chamber of a microwave plasma reactor and a microwave formed plasma is utilized to vaporize core precursor material.

Method of manufacturing core-shell particles by a microwave plasma process

Disclosed herein are embodiments of doped and undoped spherical or spheroidal lithium lanthanum zirconium oxide (LLZO) powder products, and methods of production using microwave plasma processing, which can be incorporated into solid state lithium ion batteries. Advantageously, embodiments of the disclosed LLZO powder display a high quality, high purity stoichiometry, small particle size, narrow size distribution, spherical morphology, and customizable crystalline structure.

Lithium lanthanum zirconium oxide (LLZO) powder

Systems, methods, and devices are disclosed for producing quantum particles (e.g., quantum dots) having a uniform size by vaporization of molten precursor droplets. More particularly, the present technology produces quantum dots by melting or liquefying solid and substantially pure precursor materials followed by production of uniformly sized droplets of molten precursor by use of a droplet maker into a microwave generated plasma torch.
