Ammonia → Indium tin(4+) hydroxide (1/1/7)

An aqueous indium chloride (InCl3) solution (containing 18 g of In metal) (50 mL) was mixed with 3.6 g of tin dichloride (SnCl2·2H2O) and the obtained mixed aqueous solution and an aqueous ammonia (NH3) solution were simultaneously added dropwise in 500 ml of water. After adjusting to pH 7, the mixture was reacted at a liquid temperature of 30° C. for 30 minutes. The thus obtained precipitate was repeatedly subjected to inclination washing with ion-exchange water. After resistivity of the supernatant liquid reaches 50,000 Ω·cm or more, a precipitate (In/Sn co-precipitated hydroxide) was separated by filtration to obtain a co-precipitated indium tin hydroxide whose dry powder has a persimmon tone.
