Abstract
Proposed is a method for manufacturing a spherical YOF-based powder. Specifically, proposed is a method for manufacturing a spherical YOF-based powder. The YOF-based powder injected into the plasma jet and melted into the refrigerant in a droplet state is sprayed and quenched, thereby improving density and controlling the component ratio through particle spheroidization.
