In order to fabricate a high density sintered body of ITO, nano-sized ITO powders were synthesized by coprecipitation methods. Aqueous solutions of indium and tin salts were mixed and coprecipitated by changing their pH. Coprecipitated ITO powders possessed 20-30 nm crystallite size and a relatively high BET value $(35m^{2}/g),$ however, aggregation of particles were occurred. Therefore, a novel recrystallization technique was applied in order to eliminate the aggregates. The recrystallized ITO material consists of a little bit larger needlelike crystals, $20nm{ imes}80nm$, and it possesses a higher BET value $(57m^{2}/g)$ compared to the plain coprecipitated material $(35m^{2}/g),$. Metastable phase formation and higher content of aggregated particles were observed in the coprecipitated materials. Densification was $95{\%};to;98{\%}$ complete after 5 hour sintering at $1500^{circ}C$ for the recrystallized powders while densities of the coprecipitated powders were below $75{\%}.$
