What are the specific uses of graphite carbon rods?

1. Application in the atomic energy industry and the national defense industry: Graphite has a good neutron reducing agent and is used in atomic reactors. Uranium-graphite reactors are currently used in many atomic reactors. As the deceleration material of the power reactor, it should have the characteristics of high melting point, stability and corrosion resistance. Graphite can fully meet the above requirements. Graphite used in atomic reactors requires very high purity, and impurities should not exceed a few tens of parts per million. In particular, the boron content should be less than 0.5ppm. Graphite is also used in the defense industry to make nozzles for solid fuel rockets, nose cones for missiles, parts for space navigation equipment, heat insulation and radiation protection.

2. As a refractory material: Graphite and its products have the characteristics of high temperature resistance and high strength. They are mainly used in the metallurgical industry to manufacture graphite crucibles.

3. Conductive materials: used in the electrical industry to make electrodes, carbon rods, carbon tubes, brushes, mercury rectifier positive electrodes, graphite washers, telephone accessories, TV picture tube coatings, etc. As a wear-resistant lubricating material, graphite is often used as a lubricant in the machinery industry. Lubricating oil usually cannot be used under high-speed, high-temperature, and high-pressure conditions, but graphite wear-resistant materials can slide at high speeds at temperatures of 200 to 2000°C without the use of lubricating oil. Many equipment conveying corrosive media are made of graphite materials, such as piston cups, sealing rings and bearings. Graphite emulsion is also a good lubricant for many metal processing (wire drawing, tube drawing).
