MOLD FOR MASS PRODUCTION OF CERAMIC POWDER USING SPARK PLASMA SINTERING

摘要

PURPOSE: A mold for mass synthesis of ceramic powder by spark plasma sintering is provided to uniformly mass synthesize ceramic powder by forming a plurality of pipes in which material powder is loaded. CONSTITUTION: A mold for mass synthesis of ceramic powder by spark plasma sintering comprises a body(101) which includes more than two pipes in which material powder is loaded and a pair of metal covers(102,103) which are respectively in contact with top and bottom parts of the body. The amount of raw material for the sintering of spark plasma is controlled by adjusting the height of the mold. Amounts of current and voltage for powder synthesis are minimized by forming one or more processing portions between the pipes so that the cross section of the mold body can be reduced. The peripheral or inner circumferential part of the cross section of the body has either a circular, ellipsoid, or polygonal shape.
