ABSTRACT:
According to the method, an aqueous salt solution containing either tin, indium or both, are mixed with an alkali to produce a slurry containing precipitated particles. Then, the slurry is maintained at a predetermined temperature range for a time sufficient to convert the precipitated particles to larger size particles by coagulation or agglomeration. The resulting slurry is then dried and calcined to produce a mixed power. The mixed power is ball milled, press molded and/or cold isostatic press (CIP) molded. The molded body is then sintered to form an ITO sintered body. The ITO sintered body obtained by this process offers superior sinterability whose theoretical density can reach more than 95%.
