PURPOSE:To efficiently form a homogeneous inorganic product by a method wherein a top force and a bottom force, either one of which is water permeable, are employed so as to dewater by taking advantage of the water permeability of the force and, in addition, the supply of stock slurry is controlled so as to keep the pressure in a forming space at a certain value. CONSTITUTION:Under the state that forces are closed, stock slurry 30 is forced from a screw extruder 23 in a forming space, which is made by forming recesses 3a and 13a. The moisture in the stock slurry 30 is extracted by suction through suction and compression pipes 4 and 14 of the top force and of the bottom force. The resultant lowering of the pressure in the forming space is detected with a pressure sensor 26 so as to supply the stock slurry 30 from the screw extruder 23 until the pressure in the forming space keeps a certain value. An obtained compact has favorable state with neither pore nor void developed therein.
