Abstract: Conventional carbon products require complicated methods and long synthesis cycle due to un.stable quality and high cost of the products. Evenly mixed carbonaceous powder and coal tar pitch binderwere pressed into a mold, while temperature was controllable by using spark plasma integrated applicationsystem in which the current, voltage and pulse frequency were regulated. Compression bulks were sin-tered to form sintering bulks with certain volume density and mechanical strength. Plasma sintering meth.od breakthroughs the defects of traditional craftsmanship and can shorten synthesis cycle, which is an en-vironmental friendly method and expected to be used in carbon industry in the future.

Key words: plasma, sintering, carbon, molding, coal pitch binder
