Graphite products are products made from graphite, a form of carbon. Here is an English introduction to graphite products:
Properties of Graphite Products
- Excellent thermal conductivity: Graphite products have high thermal conductivity, enabling rapid heat transfer and uniform heating. This property makes them ideal for applications such as heating elements in various devices and as materials for making cooking utensils like graphite pans and baking trays, which can heat up quickly and ensure even heating of food1.
- Good chemical stability: Graphite is chemically stable at room temperature and is not easily corroded by strong acids, alkalis, or organic solvents. Therefore, graphite products can be used in harsh chemical environments, such as in the production of chemical reactors, heat exchangers, and other equipment that need to resist corrosion1.
- High-temperature resistance: Graphite can maintain good performance at high temperatures. It has a high melting point and can withstand high-temperature environments without significant deformation or damage. This makes it suitable for use in high-temperature industrial processes, such as in metallurgy, where it can be used as a refractory material to line furnaces13.
- Self-lubricating property: The layered structure of graphite allows the layers to slide relatively easily, giving it excellent self-lubricating properties. Graphite products are often used as lubricants in mechanical equipment, reducing friction and wear between moving parts and prolonging the service life of the equipment3.
Applications of Graphite Products
- In the metallurgical industry: Graphite is used in the production of refractory materials, such as refractory bricks, crucibles, and continuous casting powders. These materials are essential for high-temperature smelting and casting processes in the metallurgical industry. For example, graphite crucibles are widely used for melting metals due to their high refractoriness, low thermal expansion, and good thermal shock resistance12.
- In the electrical industry: Graphite is a good conductor of electricity and is widely used in the electrical industry. It is used to make electrodes, brushes, carbon rods, carbon tubes, and the positive electrodes of mercury rectifiers. Graphite electrodes are particularly important in the smelting of various alloys and iron alloys, where they conduct electricity and generate arcs to convert electrical energy into heat energy12.
- In the mechanical industry: Graphite products are used as wear-resistant and lubricating materials in mechanical equipment. Graphite bearings, piston rings, and seals made of graphite are widely used in machinery to reduce friction and wear, and they can operate without the need for additional lubricants under high-speed, high-temperature, and high-pressure conditions12.
- In the nuclear industry: Graphite has good neutron deceleration performance and is used as a neutron moderator in nuclear reactors. Uranium-graphite reactors are a common type of atomic reactor that uses graphite for this purpose. Graphite used in nuclear reactors requires high purity and strict quality control to ensure its performance and safety12.
- In other fields: Graphite products also have applications in the aerospace, defense, and semiconductor industries. For example, in the aerospace industry, graphite is used to make some special parts due to its high-temperature resistance and lightweight properties. In the semiconductor industry, graphite is used as a heat sink or substrate material in some high-temperature processing equipment
