Graphite and It's Uses in Making a Graphite Furnace2014-06-05
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. In most cases, this mineral is not affected by reagents or acids hence it can be used in different chemical processes as well.
Several other support objects such as crucibles, furnace parts, foundry accessories, degassing tubes, trays 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.

There are various types of furnaces that are supplied to industries. Some of the common examples would be front-loading horizontal furnaces, bottom-loading, front-loading and bell-loading types, vacuum furnaces, autoclaves among many others. Sometimes users have lack of enough space on floor or have low overhead clearance, hence a manufacturer of furnaces should take into account such common limitations and provide suitable solutions for the same. Hence, a custom furnace is the best answer to concerns relating to space, energy and processing.

Whether it is a graphite furnace or any other type of furnace, ancillary items and accessories are required with each of them. These include cart systems, work racks, retorts, muffle boxes, scrubber systems, gas controls etc. All of these auxiliary items can be purchased from the firm manufacturing your furnace. Even if it is a custom furnace that you are opting for, all these support devices need to be purchased at the outset. So, you can carry out all your operations such as de-binding, sintering, brazing, bonding, meting and many other things in a highly effective manner.
