The structure of the graphite plate is an atomic crystal, and the carbon atoms are connected by covalent single bonds, resulting in a smooth hexagonal porous structure. Because the covalent single bond is a kind of ionic bond with very high bond energy, it requires relatively high kinetic energy to be destroyed, so the graphite plate is relatively high temperature resistant.
Generally, ordinary graphite plates can withstand high temperature 1200℃, and there is no problem in the application of high-precision parts processing, electric discharge wire cutting, metallurgical industry forging and other industries; The heat-resistant graphite plate with good performance is made of high-quality graphite carbon material, which effectively reduces the porosity, improves the bulk density, has better temperature resistance, and can withstand the high temperature of 3000℃.
