Abstract
Proposed models are used for forming into destined shapes liquid, slurry, soft, sheet or lump materials, and are provided with endurance for many times of use and excellent permeability. A basic feature is that aggregates are ferrous or non-ferrous metallic grains and ceramic grains, to which a binder contained in evaporating or consumable substance is added and kneaded, and sintered. The mode has a close hardened layer scattered with metallic oxides on at least a shell. The hardened layer has fine air vents in its thickness. The whole body of a model is 5 to 60% of porosity and more than 100 Kg/cm.sup.2 of compression strength.
