Various black silicon carbide manufacturers in China are producing this material to use as refractory material and metallurgical additive. This material has high hardness and is very useful for abrasive applications. In fact, this type of abrasive has higher hardness than corundum abrasive. However, its price is relatively high.
Graphene from petroleum coke has many applications, including energy storage, medicine, and electronics. Researchers have developed a method of separating graphene sheets from petroleum coke by electrochemically treating it.
Graphene from petroleum coke has a high electrical conductivity (50 siemens/meter), which is comparable to electrodes in lithium-ion batteries. It can be upgraded to a higher conductivity with heat treatment, called annealing. This process has been demonstrated for one-to-one molar carbon/silica powder mixtures using simultaneous thermogravimetric analysis and mass spectroscopy.
The silicon carbide process involves heating petroleum coke to 2500 degrees Celsius and using a graphite electrode in the furnace center to produce high-quality crystals. Large crystals are then segregated by high-intensity magnetic separators. These crystals are subsequently cleaned of magnetic impurities.
The proportion of silicon dioxide to carbon in the raw material is usually about one to two percent above the stoichiometric amount. This proportion is reduced by the presence of sulfide ions, which act as reducing agents.
Among the many types of refractory material, black silicon carbide is one of the most widely used. It is a type of silicon carbide that is made from petroleum coke or quartz sand. These materials have high hardness, which allows them to be used for a variety of applications, including machining, metallurgical beneficiation, and abrasive materials.
