High purity graphite (fine-grained synthetic graphite), which is usually available in the shape of block or rod, is of the following physical and chemical properties: high strength, high density, high temperature resistance, oxidation resistance, erosion resistance, and so on. It is mainly used for electron discharge machining mold, sintering mold, continuous casting graphite jig, graphite crucible, crystallizer, making all kinds of graphite products, etc. The carbon content is up to 99.9%, and the particle size is about 325 mesh. The size of graphite block: 200~850 x 120~320 x 50~200mm; the size of graphite rod: ª¦110~630 x 250~600mm.
