The graphite content of more than 99.9% purity graphite called graphite. With excellent electrical conductivity, thermal conductivity, pressure resistance, low coefficient of expansion,high volume density, low resistivity, anti-oxidation, corrosion resistance,high temperature, electrical the advantages of good self-lubricating properties and processability. Good chemical resistance; can be used in various chemical reactions crucibles, tubes and the like. The high thermal conductivity and thermal stability; melting gold, silver and other high-temperature melting products sufficient mechanical strength and impact resistance; Easy machining, can be processed into a variety of geometric shapes. Graphite sheet for silicon carbide furnace, graphite furnace and other metallurgical furnace, resistance furnace lining and as a conductive material, and impervious graphite heat exchangers. Widely used in electronics, metallurgy, chemical industry, iron and steel, product quality, performance and stability.
