MANUFACTURE OF POROUS METAL

PURPOSE:To manufacture a porous metal incorporated with many closed pore as for every metals from high m.p. metals to low m.p. metals, to optionally control the size of the closed pores and to uniformize the distribution of the pares. CONSTITUTION:Many hollow spheres having the m.p. higher than that...

Zusammenfassung:	PURPOSE:To manufacture a porous metal incorporated with many closed pore as for every metals from high m.p. metals to low m.p. metals, to optionally control the size of the closed pores and to uniformize the distribution of the pares. CONSTITUTION:Many hollow spheres having the m.p. higher than that of an objective metal, e.g. hollow spheres 1 constituted of ceramics such as alumina are filled into a mold 2, and after that, the objective metal is filled into the space between the hollow spheres 1 all around to manufacture a porous metal incorporated with many closed pares.
