Graphite micro powder

As Refractory Materials:
Graphite and its products possess high-temperature resistance and high strength, making them ideal for refractory applications. In the metallurgical industry, graphite is mainly used to manufacture graphite crucibles. It is also commonly used as a protective agent for steel ingots and as a lining material for metallurgical furnaces.

As Conductive Materials:
In the electrical industry, graphite is widely used to produce electrodes, brushes, carbon rods, carbon tubes, anodes for mercury rectifiers, graphite gaskets, telephone components, and coatings for television picture tubes.

As Wear-resistant and Lubricating Materials:
Graphite is often used as a lubricant in the machinery industry. Lubricating oils may not perform well under conditions of high speed, high temperature, and high pressure, but graphite wear-resistant materials can function efficiently under such conditions at temperatures between 200–2000 °C without the need for lubricating oil. Many devices that transport corrosive media utilize graphite components such as piston cups, sealing rings, and bearings, which operate without lubrication. Graphite emulsion is also an excellent lubricant for many metalworking processes like wire drawing and tube pulling.

Excellent Chemical Stability:
Specially processed graphite exhibits strong corrosion resistance, good thermal conductivity, and low permeability. It is widely used in the manufacture of heat exchangers, reaction tanks, condensers, combustion towers, absorption towers, coolers, heaters, filters, and pump components. These applications are common in petrochemical, hydrometallurgy, acid and alkali production, synthetic fiber, and paper industries, contributing to substantial savings in metal materials.

As Casting, Molding, and High-temperature Metallurgical Materials:
Due to its low thermal expansion coefficient and resistance to sudden temperature changes, graphite can be used to make molds for glassware. When used in casting, it helps achieve accurate dimensions, smooth surfaces, and high yield rates for castings, often requiring little to no further machining. Graphite is also used in powder metallurgy processes to make molds and sintering boats for producing hard alloys. Crucibles for growing single-crystal silicon, zone refining containers, support fixtures, and induction heaters are all made from high-purity graphite. Additionally, graphite is used in vacuum metallurgy as heat insulation boards, bases, furnace tubes, rods, plates, and grid shelves for high-temperature resistance furnaces.

In the Nuclear and Defense Industries:
Graphite is an excellent neutron moderator and is used in nuclear reactors, especially uranium-graphite reactors. Graphite used in nuclear applications must have high purity, with total impurity content below several dozen PPM and boron content less than 0.5 PPM. In the defense industry, graphite is used to manufacture nozzles for solid-fuel rockets, missile nose cones, parts for space exploration equipment, heat-insulating materials, and radiation shielding components.

To Prevent Boiler Scale Formation and Corrosion:
Experiments have shown that adding a small amount of graphite powder (about 4–5 grams per ton of water) to boiler water can prevent scale buildup on boiler surfaces. Additionally, graphite coatings applied to metal chimneys, rooftops, bridges, and pipelines provide anti-corrosion and anti-rust protection.

Other Uses:
Graphite is also used to make pencil leads, pigments, and polishing agents. After special processing, it can be transformed into various advanced materials for use in specific industrial sectors. In the light industry, it serves as a polishing and anti-rust agent for glass and paper. It is also an essential raw material for manufacturing pencils, ink, black paint, printing ink, synthetic diamonds, and artificial gemstones. As a highly energy-efficient and environmentally friendly material, graphite is even used in electric vehicle batteries in the U.S. With the advancement of modern science and technology, the applications of graphite continue to expand. It has become a crucial raw material in high-tech fields and plays a significant role in the national economy.
