Gas atomization process is widely used for the production of various metal and pre-alloyed powders. The process involves the disintegration of a liquid stream of molten metal into liquid metal droplets by the impingement of high pressure gas jets. The liquid metal droplets subsequently cool and solidify into metal powder particles, which can typically range from 1 to 150 µm.

After a detailed study of various atomizing processes, the cross jet gas atomizing scheme was selected for the present research work. Experiments were carried out using air and argon gas as atomizing media. Particle shape was observed using Scanning Electron Microscope. The particle size distribution was measured using the Laser Particle Size Analyzer. XRD analysis of different powder samples was carried out to measure the oxygen contents. Spherical shape particles ranging from 1 µm to 60 µm sizes were produced.
