The Main Use of Silicon Carbide

Author:Jinlin corundumTo update: 2016-10-10

Parents will tell us that a man must have skills, or in the future you will be difficult to survive, parents, then we will always be in the heart, in fact, parents say this sentence is also right, whether people or things, we should have skills, so as not to be abandoned by life. Today we want to elaborate silicon carbide is the case, because it has great use, so not be eliminated, the following is the main use of silicon carbide.
Silicon carbide, also known as emery, contains both black silicon carbide and green silicon carbide. Black silicon carbide is quartz sand, petroleum coke and high-quality silica as the main raw material, through the resistance furnace made of high temperature smelting. Green silicon carbide is based on petroleum coke and high-quality silica as the main raw material, add salt as an additive through the resistance furnace made of high-temperature smelting. So what are the main uses of silicon carbide? According to our previously mentioned the application range of the silicon carbide we can probably understand some, the following is a more specific use.
1. Abrasive
Because silicon carbide has a high hardness, chemical stability and a certain degree of toughness, silicon carbide can be used in the manufacture of cemented abrasives, coated abrasives and free grinding, to process glass, ceramics, stone, cast iron and some non-ferrous metals, cemented carbide, titanium, grinding wheel.

2. Refractory materials and corrosion-resistant materials
As the silicon carbide has a high melting point, chemical inertness and thermal shock resistance, so silicon carbide can be used for abrasive, ceramic products, firing furnace plate used in the plate and sagger, zinc vertical distillation furnace industrial silicon carbide brick, aluminum cell liner, crucible, small pieces of furnace materials, and other silicon carbide ceramic products.
3. Chemical use
Because silicon carbide can be dissolved in molten steel and molten steel from the oxygen, the reaction of metal oxides to produce carbon monoxide and silicon slag. So it can be used as a purification of iron and steel smelting, steel-making deoxidizer and cast iron tissue modifier. At the same time can also be used as raw materials for the manufacture of silicon tetrachloride.
4. Electrical purposes
Silicon carbide is used as a heating element, a non-linear resistance element and a high-semiconductor material. Heating elements such as silicon carbon rods, non-linear resistance components, all kinds of lightning-valve.
5. The other prepared into a far-infrared radiation coating or silicon carbide silicon plate made with far infrared radiation dryer.
These are the main uses of silicon carbide made by a simple overview, in fact, we do not belong to the most meticulous use of sub-law, the most detailed sub-law like application of silicon carbide in refractory. Thank you for reading, please continue to pay attention to our website! We will continue to update more information on fused alumina refractories for your reference!
