Many people erroneously believe that carbon and graphite are the same and are therefore able to be used in similar applications. In fact, carbon graphite material is made up of amorphous carbon and graphite, hence the combination of the terms in the name.
The use of amorphous carbon provides a very strong and durable foundation for the combination of the two elements of carbon. In its isolated state, this amorphous carbon is extremely resistant to wear, which makes it a good option in some limited types of applications. The big drawback with the use of amorphous carbon is the hardness of the material which increases the amount of friction if they material is moving in contact with other materials.
With the addition of graphite, which is software and naturally slides and reduces the level of friction, the carbon graphite material combines the strength and the natural lubrication of the two elements for an ideal combination in many applications.
Benefits to Consider
With the choice of carbon graphite sidewall blocks and blocks used in the construction of furnaces and metallurgical operations, the benefits from the combination of the two materials are even greater.
This is a highly corrosion resistant type of material. Different types of processing of the blocks can create those with extremely fine porosity, further reducing the risk of any type of corrosion or deterioration of the surface.
Depending on the grade of the carbon graphite material, which is based on the ratio of the two elements of carbon as well as the use of coal tar pitch used as a binder, this is also a material which can withstand very high levels of heat for extended periods of time without any damage to functionality and structure.
The use of carbon graphite, particularly the higher grades, is a top choice for any application where high temperatures, corrosion resistance, and durability are key factors for selection.
