POROUS SINTERED BODY AND METHOD OF MANUFACTURING SAME

摘要

A powder of fine particles of an electrically conductive or semiconductive material, which have a diameter of 10 mu m or less, is pressurized, and, at the same time, a pulse voltage is applied between the fine particles to produce an electric discharge therebetween. The fine particles are fused together at areas where they contact each other, thereby producing a porous sintered body. The porous sintered body is made of only an electrically conductive or semiconductive material without using any particle binders whatsoever.
