In this paper,gallium nitrate was taken as the raw material,gallium oxyhydroxide was successfully prepared by gallium salt precipitation method,and the effects of process parameters such as precipitant type,reaction temperature,pH value and gallium ion concentration on the preparation of gallium oxyhydroxide were systematically investigated.The results show that the precipitation rate of gallium reaches 79.7%,and the precipitated product is white powder of gallium oxyhydroxide under the optimal conditions of ammonia as precipitant,reaction temperature of 70℃,pH value of 8,and gallium ion concentration of 0.16 mol/L.Theβ-Ga₂O₃powder with uniform morphology and conforming to the Ga₂O₃3N standard in YS/T 741—2010 can be prepared by roasting the precipitated product at 800℃for 3 h.In this study,gallium nitrate can be efficiently converted into gallium oxyhydroxide with homogeneous morphology and size by gallium salt precipitation method,with simple process flow,low production cost,and prospect for industrialization.
