Carbon materials come in hundreds of varieties and thousands of
specifications.
- According to the material division, the carbon material can be divided into carbonaceous products, semi-graphitic products, natural graphite products and artificial graphite products.
- According to their properties, carbon materials can be divided into graphite electrode and graphite anode, carbon electrode and carbon anode, carbon block, paste products, special carbon and graphite products, carbon products for mechanical and electronic industry, carbon fiber and its composite materials and graphite chemical equipment, etc.
- According to the service objects, carbon materials can be divided into metallurgical industry, aluminum industry, chemical industry, mechanical and electronic industry and new carbon materials used in high-tech departments.
- According to the functional division, carbon materials can be divided into three categories: conductive materials, structural materials and special functional materials:
(1) conductive materials. Such as electric furnace with graphite electrode, carbon electrode, natural graphite electrode, electrode paste and anode paste (self-baking electrode), electrolysis with graphite anode, brush and EDM die materials.
(2) Structural materials. Such as duty forge, ferroalloys furnace, carbide furnace, such as the aluminum electrolytic cell lining (also called a carbonaceous refractory material), the reduction of nuclear reactor and reflective materials, rocket or missile head of department or nozzle lining materials, corrosion resistance of the chemical industry equipment, industrial machinery wear-resistant materials, steel and non-ferrous metal smelting industry continuous casting crystallizer graphite lining, Semiconductor and high purity material smelting devices.
(3) special functional materials. Such as biochar (artificial heart valve, artificial bone, artificial tendon), various types of pyrolytic carbon and pyrolytic graphite, recrystallized graphite, carbon fiber and its composite materials, graphite interlayer compounds, Fuller carbon and nano carbon, etc.
- According to the use and process division, carbon materials can be divided into the following 12 types.
(1) Graphite electrodes. It mainly includes ordinary power graphite electrode, high power graphite electrode, ultra-high power graphite electrode, anti-oxidation coating graphite electrode, graphitized block, and natural graphite electrode produced with natural graphite as the main raw material.
(2) Graphite anode. Including all kinds of solution electrolysis and molten salt electrolysis used anode plate, anode rod, large cylindrical anode (such as electrolysis of metal sodium).
(3) carbon electric (positive) electrode. It mainly includes the carbon electrode with high quality anthracite as the main raw material, the carbon anode with petroleum coke as the main raw material for aluminum electrolytic cell (i.e. pre-baked anode), and the carbon grid brick with asphalt coke as the main raw material for power supply and magnesia industry.
(4) carbon block type (metallurgical furnace with carbon refractory material). Mainly includes blast furnace using carbon block (or vibration extrusion molding carbon block and the roasting and processing, molding electric roasting hot little carbon blocks at the same time, moulding or vibration molding after roasting, the direct use of self baking carbon block, graphite block, semi graphite block, graphite a silica carbide, etc.), aluminum electrolysis cell cathode carbon block (side carbon block, carbon block at the bottom), Iron alloy furnace, calcium carbide furnace and other mineral thermal electric furnace lining carbon block, graphitization furnace, silicon carbide furnace for lining the body of the carbon block.

(6) high purity, high density and high strength graphite. It mainly includes high purity graphite, high strength and high density graphite and high density isotropic graphite.
(7) special charcoal and graphite. It mainly includes pyrolytic carbon and pyrolytic graphite, porous carbon and porous graphite, glass carbon and recrystallized graphite.
(8) wear-resistant carbon and wear-resistant graphite for mechanical industry. It mainly includes sealing rings, bearings, piston rings, slideways and blades of some rotating machinery used in many mechanical equipment.
(9) Charcoal and graphite products for electrical purposes. It mainly includes the brush of electric motor and generator, the pantograph slider of trolley bus and electric locomotive, the carbon resistor of some voltage regulator, the carbon parts of telephone transmitter, arc carbon rod, carbon arc gouging carbon rod and battery carbon rod, etc.
(10) graphite chemical equipment (also known as impermeable graphite). It mainly includes various heat exchangers, reaction tanks, condensers, absorption towers, graphite pumps and other chemical equipment.
(11) Carbon fiber and its composites. It mainly includes three varieties of pre-oxidized fiber, carbonized fiber and graphitized fiber, and carbon fiber and various resins, plastics, ceramics, metals and other forms of composite material products.
(12) Graphite interlaminar compound (also known as intercalated graphite). There are mainly flexible graphite (i.e., expanded graphite), graphite-halogen interlaminar compound and graphite-metal interlaminar compound 3 varieties. Expansive graphite made from natural graphite has been widely used as gasket material.
