AB - Gallium, a key material in TFT (Thin-Film Transistor) targets and LED (Light Emitting Diode), is highly sought after due to its scarcity, making the recovering and recycling from waste resources. This study develops a process to recover high-purity gallium contained in an alkaline electrolyte and to produce gallium oxide nanopowder for IGZO (Indium Gallium Zinc Oxide) targets. Through an investigation of the electrowinning process conditions, the effects of various process factors and the optimal conditions are identified. It is found that the concentration of NaOH significantly affects purity. By employing two rounds of electrowinning followed by acid washing, gallium with a purity of over 99.995 % is successfully recovered. Using this recovered gallium as a starting material, gallium oxide is produced via a gas-phase synthesis. It is observed that while higher temperatures increase the yield, the purity decreases. Ultimately, at 1,260°C, gallium oxide nanopowder with a purity exceeding 99.995 % is obtained with a yield close to 90 %. The galliumoxide nanopowder predominantly exhibits a size of approximately 2μm and a spherical shape, suggesting favorable characteristics for subsequent processes such as sintering.
