Refractories Materials Graphite Nanopowders
1. Particle size: 100-200nm, 300-500nm,or micron size 1um(other micron size we also could do)
2. Purity: 99.95%
3. Flake
Graphite Nanopowders Application:
1. For refractories: Graphite nature and itsproducts have high temperature, high strength, mainly used in metallurgicalindustry in the manufacture of graphite crucible, graphite used in steelmakingas a protective agent of ingot metallurgy furnace lining.
2. As the conductive material: the electrode,the positive brushes, carbon rod, carbon tube, the mercury being current,graphite gaskets, telephone parts, TV picture tubes and other coatings used inthe manufacture of electrical industry.
3. For wear and lubrication materials: graphiteis commonly used as a lubricant in the machinery industry. Lubricants are oftennot at a high speed, high temperature and high pressure conditions, andwear-resistant material may be graphite at high sliding speeds, not in thelubricating oil temperature of 200 ~ 2000 ℃.
4. Graphite has good chemical stability. Afterspecial processing of graphite, resistant to corrosion, thermal conductivity,and low permeability, it is used extensively for the production of heatexchangers, reactor, condenser, burning towers, absorber, coolers, heaters,filters pump equipment.
5. For casting, foundry, die andhigh-temperature metallurgical materials: production of carbide powdermetallurgy process, usually graphite material molding and sintering of ceramicboat. Monocrystalline silicon crystal growth crucible, regional refiningvessel, the stent fixture, induction heaters, etc. are processed usinghigh-purity graphite. Also graphite graphite can be made vacuum insulationpanels and smelting base, high temperature resistance furnace tubes, rods,plates, and other components of the grid shed.
6. For the nuclear industry and the defenseindustry: Graphite has good neutron moderator for atomic reactors,uranium-graphite reactor is used more as a nuclear reactor. Also used in thedefense industry in the manufacture of graphite nozzle solid rocket parts,missile nose cones, Astronauts equipment, insulation materials andanti-radiation materials.
7. Graphite can prevent boiler scale, inaddition to the graphite coating on the metal chimneys, roofs, bridges,pipelines can corrosion and rust.
8. Can be used pencil graphite, paint, polish.After special processing of graphite, can produce a variety of specialmaterials used in the relevant industrial sectors.
In addition, graphite or light glass and paperpolishes and rust inhibitors, is to create a pencil, ink, black lacquer, inkand synthetic diamond, diamond indispensable raw materials. It is a good energysaving materials, the United States has used it as a car battery.
