Procedure

600 g of water was added to 600 g of the diantimony pentoxide sol (specific gravity: 1.198, Sb2O5 concentration: 18.4 wt %) prepared in Preparation Example 1 for dilution. Then, an aqueous indium nitrate solution having 121.1 g of indium nitrate (In(NO3)3.3H2O, In2O3 content: 39.1 wt %, guaranteed reagent, manufactured by Mitsuwa Kagaku Yakuhin K. K.) dissolved in 100 g of water, was added thereto with stirring at room temperature. Then, the mixture was heated at 90° C. for 9 hours to obtain a mixed slurry of indium hydroxide and diantimony pentoxide. This slurry had an In2O3 concentration of 3.3 wt %, a Sb2O5 concentration of 7.8 wt % and an In2O3 /Sb2O5 molar ratio of 0.5.
