Product Description
Graphite is a soft, slippery, greyish-black material that has a metallic luster. It is opaque to light and is a good conductor of electricity and heat. Most of the time, graphite is just referred to as carbon. Under vacuum or inert gas, graphite is very temperature-resistant which makes it a potential material for high temperature applications.
By heating graphite up to 3000 °C at Carbotech furnace, its properties are enhanced. Consequently, heat treatment of graphite is an emerging market and graphite has become a vital material for numerous applications worldwide. Graphite is regularly used as a part of composite materials.
In the automotive sector, for instance, graphite is used for manufacturing brakes, clutch facings, mechanical seals, brake linings, friction components, engine parts and also as a substitute for aluminum or steel in car frames.
The newest most remarkable field of application is the lithium-ion batteries of small electronic devices, laptops, tools and electrical cars. Another area is the manufacture of alkaline batteries.
Rare but very prominent applications are in carbon brake disks in Formula One racing cars, or as part of reinforced carbon which is used for wing leading edges and the nose cone of the Space Shuttle orbiter to resist huge temperatures during re-entrance into the earth's atmosphere.
The graphitization process involves a restructuring of the molecular structure of the carbon material, graphitization generally occurs at high temperature (up to 3000ºC (5430ºF)). Carbotech high temp graphite furnaces can reach 3000ºC, which can make carbon atoms reaarange and form layered crystal planes, which greatly improve properties such as good electrical and thermal conductivity, low friction and excellent lubrication.
CB-Lab 3000 degree high temperature laboratory furnace: which use advanced induction heating method, with graphite crucible inside chamber surrounded by graphite felt for insulation,induciton coild generates a magnetic field, so can reach max 3000ºC quickly and with excellent temp uniformity. The high-ferformance lab vacuum graphitization furnace is ideal for the requests of graphite material graphitization in university, laboratory and scientific research institutions.
