Carbon and graphite materials are non-metallic solid materials dominated by carbon elements, among which carbon materials are basically composed of non-graphitic carbon materials, while graphite materials are basically composed of graphitic carbon materials. For simplicity, carbon and graphite materials are sometimes referred to as carbon materials (or carbon materials).

Carbon products can be divided into graphite electrode, carbon block, graphite anode, carbon electrode, paste, electric carbon, carbon fiber, special graphite, graphite heat exchanger, etc. Graphite electrodes can be divided into ordinary power graphite electrodes according to the allowable current density. High power electrode, ultra high power electrode. According to the use of carbon block can be divided into blast furnace carbon block, aluminum carbon block, electric furnace block, etc. Carbon products can be divided into carbon products, graphite products, carbon fibers and graphite fibers according to the processing depth. According to the different raw materials and production process, carbon products can be divided into graphite products, carbon products, carbon fibers, special graphite products, etc. According to the ash content, carbon products can be divided into more ash products and less ash products (ash content is less than 1 %).
