Refractory alloy powders are mainly W, Mo, Ta, Na, etc. Molybdenum and tungsten are two materials that will be optimized for use in additive manufacturing. The spherification of metal powders involves passing the raw material through a high-energy gas, during which the material is melted and formed into spherical particles. Such metal particles are well suited for additive manufacturing because they have better flowability.

Such spheroidized powders offer high processability, significant performance improvements when used in applications such as binder injection, powder bed fusion, and direct fusion deposition, and they produce spherical particles with improved flow, high apparent density, and high purity.
