Claim 8:
9. A method for manufacturing a spheroidized metal nitride powder, the method comprising:
providing a metal powder as a feedstock to a microwave plasma torch;
introducing the feedstock into a microwave plasma generated by the microwave plasma torch, the microwave plasma generated by subjecting a nitrogen-containing gas to microwaves from a microwave power source; and
forming the spheroidized metal nitride powder, the spheroidized metal nitride powder formed by at least partially melting the feedstock and initiating a chemical reaction between the feedstock and the nitrogen-containing gas within the microwave plasma torch, and the spheroidized metal nitride powder comprising one or more particles, the one or more particles comprising metal nitride throughout a complete mass of the one or more particles,
wherein the one or more particles comprise a pre-determined concentration of nitrogen to form a TiN, Ti2N, or TiN2 phase within the one or more particles by controlling an amount of the nitrogen-containing gas and a residence time of the feedstock in the reactive plasma gas.
