Procedure

An aqueous SnCl4 solution having a concentration of 55% was prepared using tin tetrachloride as a tin compound. 14.4 g of the aqueous SnCl4 solution and 90 mL (a content of In was 35 g) of indium chloride (InCl3) were mixed to prepare a mixed aqueous solution. 0.6 L of an aqueous alkali solution containing 190 g of an aqueous ammonium hydrogen carbonate (NH4HCO3) was added to the mixed aqueous solution to obtain a mixture (reaction liquid). The pH of the reaction liquid was adjusted to 8, and a temperature of the liquid was adjusted to 30° C., and the mixture was caused to react for 30 minutes. A generated precipitate was repetitively subjected to inclination washing by using ion exchange water. When resistivity of the supernatant liquid became 50,000 Ω·cm or more, the precipitate (In/Sn coprecipitated hydroxide) was filtered to obtain a coprecipitated indium tin hydroxide. This coprecipitated indium tin hydroxide was white.
