What is Graphite Products
Graphite products has many excellent properties, it is widely used in metallurgy, machinery, electrical, chemical, textile, national defense and other industrial sectors. It can be used as refractory material. Graphite products maintain the original chemical properties of flake graphite and have strong self-lubricating properties. The characteristics of graphite powder are high-strength acid resistance, corrosion resistance and high temperature resistance of 3000 °c and low temperature resistance of -204 °c. At the same time, its compressive strength is greater than 800kg/cm2, and it is anti-oxidation. It loses 1% of its weight in 450 °c air and has a rebound rate. 15-50% (density 1.1-1.5).
Advantages of Graphite Products
Graphite products have strong anti-oxidation and reduction effects
Products, especially graphite mattresses, can produce negative oxygen ions after being heated to activate the surrounding items, maintain human health, effectively prevent aging, and make the skin full of luster and elasticity.
Graphite products have good thermal conductivity, fast heat transfer, uniform heating, and fuel saving
Baking pans and pots made of graphite heat up quickly, and the cooked food is evenly heated, cooked from the inside out, and the heating time is short. Not only does it taste pure, but it can also lock in the original nutrients of the food. We have done experiments. When grilling meat with a graphite baking tray, the induction cooker can be preheated in only 20-30 seconds when it is first turned on to a high fire.
Graphite products have chemical stability and corrosion resistance
Graphite has good chemical stability at room temperature and is not corroded by any strong acid, strong alkali and organic solvent. Therefore, even if graphite products are used for a long time, there is little wear and tear, as long as they are wiped clean, they are still as new.
Graphite products are environmentally friendly and healthy, without radioactive pollution and high temperature resistance
Carbon has to go through at least a dozen days and nights of graphitization in a high temperature environment of 2000-3300 degrees to become graphite. Therefore, the toxic and harmful substances in graphite have already been released, and it is stable at least within 2000 degrees.

What Products can be Made From Graphite
Graphite is a versatile material with a wide range of applications in various industries. It can be used to manufacture a variety of products due to its unique combination of properties, including high temperature resistance, electrical conductivity, lubricity and chemical inertness.
Graphite electrodes: Graphite electrodes are a key component of electric arc furnaces (eaf) for steelmaking and are also used in other high-temperature applications such as electrical discharge machining (edm) and glass melting.
Heat exchangers: Graphite is used to make heat exchangers for processes that require resistance to high temperatures and corrosive environments, such as chemical processing.
Lubricants: Graphite’s natural lubricating properties make it a key ingredient in a variety of lubricants and greases, especially in high temperature and high pressure applications.
Seals and gaskets: Graphite gaskets and seals are used in applications that require high temperature and chemically resistant sealing materials, such as the petrochemical industry.
Bearings and bushings: Graphite can be used to make self-lubricating bearings and bushings to reduce friction and wear in machinery.
Crucibles and molds: Graphite is used in casting applications as a material for crucibles and molds used to melt and cast metals and alloys.
Chemical processing equipment: Graphite is used to make a variety of components, including pipes, valves and reactors, for handling corrosive chemicals and high-temperature processes.
Anode: Graphite anodes are used in electrochemical processes such as electroplating and water treatment.
Thermal insulation: Graphite-based materials are used for thermal insulation in high-temperature applications, including furnaces and aerospace components.
Electrochemical cells: Graphite is used as an electrode material in electrochemical cells and batteries, particularly in alkaline cells and fuel cells.
High temperature crucibles: High temperature crucibles made of graphite are used in a variety of chemical and materials research in laboratory and industrial settings.
Heat sink: Graphite sheets or plates are used as heat sinks in electronic equipment to dissipate the heat generated by components such as microprocessors.
Graphite products can play a self-lubricating effect, mainly because the bonding force between the graphite layer and the layer is weak, and it is easy to slide relatively. When graphite forms a thin layer of graphite on the metal surface, it becomes the friction between graphite and graphite. In the presence of water and air, the working surface of the graphite product adsorbs water and gas molecules, which increases the distance between the layers and weakens the attractive force between the layers. In addition, water and gas molecules occupy the positions of free bonds on the edge of the graphite. Both of these factors make it difficult for the two friction surfaces of graphite to adhere.
It can be seen that the self-lubricity of graphite products depends on the presence of water and air.
