PURPOSE:To change the powdery sublimate substance only in the warming and heating conditions and to obtain the molded articles having various kinds of properties in the same apparatus by warming the powdery sublimate substance charged to the inside of a molding cylinder at 0-120 deg.C and molding it under the pressurizing of 50-600kg/cm<2>. CONSTITUTION:The powdery sublimate substance is charged into the inside of a molding mold to perform the molding by warming it at 0-120 deg.C and adding 50-600kg/cm<2> pressure thereto. For example, powdery iodine of 20-60 mesh is charged into a hole 2 and heated at the temp. of <=120 deg.C with a heating apparatus 4 and pressurized in 50-600kg/cm<2>. In this case, the molded article having 20mm. diameter and 1.2-1.6mm. thickness is obtained by charging 13.8g powdery iodine into the inside of the hole 2 of a bottom force 3. The molded article having 3.0-3.5g/cm<3> density is a porous molded article and optimum in case of being used for the catalytic reaction of liquid and gas, etc., or as a catalyst. |
