Synthesis of indium sulfate

Under the condition of heating, metal indium or In2O3 is dissolved in large excess dilute sulfuric acid and concentrated at 50℃, the crystallization of In2(SO4)3·H2SO4·7H2O can be precipitated. The crystals were filtered out with a glass sand core funnel, washed with glacial acetic acid and dried. Anhydrous indium sulfate can be generated by heating the acid salt until no sulfuric acid is volatilized (450℃, about 6 hours). Alternatively, a solution of indium sulfate can be prepared first, and the solution can be concentrated and crystallized into a trapezium crystal of In2(SO4)3·5H2O. This crystallization is decomposed to form anhydrous indium sulfate by heating it at a temperature of about 500 ° C for 6 hours.
