Graphite and It's Uses in Making a Graphite Furnace

Graphite is a mineral that's an allotrope of carbon. It its natural form, it is a great conductor of heat as well as electricity, making it suitable for high-temperature industrial processes. These very attributes make it best suited for manufacturing a graphite furnace.
Several other support objects such as graphite crucibles, graphite heat exchanger, foundry accessories, graphite electrodes, graphite tubes and boats etc are also made of graphite. All of these items can withstand high temperatures over an extended period of time. Electrical furnaces are also heavily dependent on this mineral for various types of components.
This mineral sees a heavy demand as it is used for manufacturing furnace linings, which help achieve highest temperatures. The internal heater elements are made of graphite to achieve consistent and well-distributed heating operations. However, it must be noted that in some cases, this mineral could pose a risk of carbon reaction or particulate contamination when used in conjunction with a particular product. The solution to this would be to provide for refractory metal hot-zones.
Besides, furnaces that are high temperature and need to use all-metal would usually comprise elements and heat shields made of molybdenum or tungsten as elements and heat shields. This enables high-purity, high-vacuum environments, and temperatures up to 2100 degrees centigrade. Applications such as metal injection molding stand to benefit from the use of a low-cost graphite heaters and insulation. By using a graphite furnace for this purpose, precise control over temperatures, gas flows, vacuum, and partial pressure levels can be achieved.
