A Comprehensive Guide to Isostatic Graphite Materials
Isostatic graphite, is a graphite material produced by a specialised isostatic manufacturing process. The process applies high pressure uniformly to graphite particles in all directions to form a graphite material with isotropic properties.
Characteristics:
Isotropic Structure: Isostatically pressed graphite has an isotropic structure, which means it exhibits consistent properties in all directions. This consistency allows it to exhibit excellent thermal and electrical conductivity in all directions.
High Density: The compression of the graphite particles during the isostatic pressing process gives isostatically pressed graphite its high density. This high density gives it excellent strength, stability and resistance to thermal shock.
Fine Grain Structure: Isostatically pressed graphite exhibits a fine grain structure, which contributes to its mechanical properties and surface finish.
Areas of application:
Electrode for Electrical Discharge Machining: Isostatic graphite is widely used in Electrical Discharge Machining (EDM), especially as an electrode. Its isotropic structure enables precise and efficient machining, resulting in high-quality machined surfaces.
Semiconductor manufacturing: In the semiconductor industry, isostatic graphite is used in processes such as ion implantation, sputtering and chemical vapour deposition. Graphite’s high purity, thermal conductivity and stability make it ideal for handling and processing semiconductor wafers.
Aerospace and defence: Isostatic graphite has a variety of applications in aerospace and defence, including rocket nozzles, heat shields and thermal management systems. Its high strength, lightweight and high-temperature resistance make it ideal for these demanding environments.
With its multiple advantages, isostatic graphite plays a key role in a number of industrial sectors, driving innovation and development of high-performance materials technology.
