Spherical powder preparation primarily uses atomization (gas, water, plasma) and plasma spheroidization to melt and rapidly solidify metal into spheres, while other methods like sol-gel, gas-phase synthesis, and centrifugal methods suit nanoparticles or specialized applications, all aiming for high sphericity crucial for additive manufacturing, controlling parameters like gas pressure, rotation speed, or plasma power to tailor powder characteristics.  

Common preparation processes for spherical powder include Water Atomization(WA)，Gas Atomization(GA)，Vacuum Induction Melting Inert Gas Atomization (VIGA)，Electrode Induction Melting Gas Atomization (EIGA)，Plasma Atomization (PA)，Plasma Rotating Electrode Process (PREP)，Radio Frequency (RF) Plasma Spheroidization，
