PURPOSE: To provide a large-sized seamless high-density sintered compact by compacting to slurry by a high pressure slip casting process. CONSTITUTION: The slurry, containing indium type oxide powder with (5 to 50)m<2> /g BET value as solid, is compacted. A mold is prepared by using a complex consisting of h-BN type complex ceramics and/or synthetic resin and inorganic compound powder. The pore diameter and pressure-resisting strength of the mold are regulated to 0.3-10μm and >=300kg/cm<2> , respectively. The slurry is poured into the mold and a pressure of >=2×10<5> Pa is directly applied to the slurry to mold it. By using the high pressure slip casting process, compacting velocity can be increased to a greater extent and a green compact reduced in water content can be formed in a short time, and further, compacting density can be increased. The green compact is dried and sintered, by which the sintered compact for transparent conductive film formation can be obtained. |
