01 High-Density Isotropic Graphite

• Isotropic graphite not only has the excellent properties of conventional graphite, such as heat resistance, chemical resistance, and thermal conductivity, but its thermal and mechanical properties are not directional due to its isotropic structure.
• Extruded graphite is divided into anisotropic and isotropic graphite, which are used according to their mechanical properties and application requirements. Isotropic graphite has a fine-grained structure compared to anisotropic graphite and is a high-density, high-strength product.
• General graphite molded bodies are manufactured by high-pressure molding and high-temperature firing using a mixture of coke filler and binder pitch, but as the binder pitch solidifies during the firing process, pores are generated inside, making it impossible to achieve high density. To solve this problem, composite particles of filler coke and binder pitch are generally obtained by mixing the filler coke and binder pitch, cooling and grinding them into a fine powder, and then high-pressure molding them through isostatic molding, etc. to achieve a final density of 1.90g/㎤ after firing, and it is impossible to produce high-density products in this way.
• By manufacturing isotropic graphite molds without the use of binder materials, the present technology has the effect of producing isotropic graphite molds in a short time without the problem of insufficient isotropy due to the heterogeneity of the binder components that occurs during firing and graphitization. In addition, because it is made exclusively of carbon powder and has excellent homogeneity, it has a high density of more than 1,95 g/cm2 and a Shore hardness of more than 80.

• We have secured the technology to produce high-density isotropic graphite with a density exceeding 1.95g/cm³ and enable near-net shaping.
• This product is particularly well-suited for military applications.
