High-purity graphite blocks

High-purity graphite blocks are a special material with a carbon content of ≥99.9%, featuring high-temperature resistance (melting point 3850℃), excellent electrical and thermal conductivity (thermal conductivity 580W/(m·K)), and chemical inertness. Its density is 1.7-1.8g/cm³, and it can be formed by molding or isostatic pressing. It is widely used in semiconductor wafer manufacturing (with a thermal deformation of 0.003mm/300mm), crucibles for photovoltaic single crystal furnaces, and high-temperature resistant components for aerospace.
