Graphite rod and graphite plate is one of the crystalline minerals of carbon element. It has excellent properties such as lubricity, chemical stability, high temperature resistance, electrical conductivity, special thermal conductivity and plasticity, coating property, etc. its application fields are very wide. Graphite rod and graphite plate are mainly used as refractory materials in metallurgical industry, as casting mold and antirust coating in casting industry, and in producing carbon electrode and electrode carbon rod in electrical industry, Batteries, graphite rods and plates made of graphite can be used as TV picture tube coating, carbon products can be used for generators, motors, communication equipment and many other aspects; in the mechanical industry, it is used as a lubricant for high-speed machinery such as aircraft, ships, trains, etc.; in the chemical industry, it is used to manufacture various corrosion-resistant utensils and equipment, In addition, graphite rods and graphite plates are also used as polishing and antirust agents for glass and paper in light industry, making pencils, ink and black paint, Raw materials for ink and synthetic diamond.
Graphite Male – Female Rods has a typical layered structure, the carbon atoms are arranged in hexagonal network layer, and the carbon atoms on the surface network node are relative to the center of the upper and lower adjacent layer grids. The graphite 2H polytype with the repeating layer of 2 belongs to the hexagonal crystal system, which is commonly referred to as the graphite rod and graphite plate; if the repeating layer is 3, it is the graphite 3R polytype, belonging to the cubic crystal system, In the crystal structure of graphite, the coordination number of carbon atoms in the layer is 3, with covalent metal bond, the spacing is 0.142 nm, and the layer to layer is connected by molecular bond with the spacing of 0.340 nm. This special crystal structure and chemical bonding property make graphite have some special technological properties
