PURPOSE:To produce thin-wall carbon parts with high efficiency, by preparing an electrically conductive base material of a desired shape, and forming a uniform carbon powder layer on the base material utilizing the principle of electrophoresis. CONSTITUTION:Fine carbon powder capable of being sintered or fine powder consisting essentially thereof or a raw material powder containing the same and further a sintering assistant, binder, etc. is kneaded with a carrier ionizable in a liquid. The resultant mixture powder containing the carrier stuck thereto is dispersed in the liquid, and a DC voltage is applied across an electrically conductive base material and a counter electrode dipped in the liquid to deposit the raw material powder containing the carrier stuck thereto on the electrically conductive base material. The base material is removed from the deposited material consisting of the raw material powder and the carrier, and the carrier in the deposited material is carbonized or decomposed and volatilized. The resultant material is then fired and sintered to afford the aimed carbon parts. |
