Silicon Carbide also has the resistivity necessary to perform as a semiconductor material. Silicon Carbide Silicon carbide is not only the lightest, but also the hardest ceramic material and has excellent thermal conductivity, low thermal expansion and is very resistant to acids and lyes.

Why Silicon-Carbide Semiconductors Have a Bright Future They are small, powerful and extremely efficient: semiconductors made of silicon carbide could help take the power electronics in batteries and sensors to the next level—making a significant contribution towards the electromobility breakthrough and supporting digitization in the industrial sector.

Silicon carbide can be used in the production of graphene because of its chemical properties that promote the epitaxial production of graphene on the surface of SiC nanostructures. When it comes to its production, silicon is used primarily as a substrate to grow the graphene.

Silicon carbide is used as a sensing device in chemical production, and in turbine or engine testing industries to detect flammable and combustible gases in harsh, high-temperature, and corrosive environments [3]. Electronics. Silicon carbides are used as semiconductors in many circuit elements due to their high voltage resistance.

That’s why SiC is used not only as a semiconductor material for varistors, but also for very fast Schottky diodes, blue-light-emitting diodes and junction FETs. Due to the excellent thermal conductivity of SiC as a substrate, semiconductor circuits made of SiC allow temperatures of up to 600 °C / 1112 °F.

Silicon carbide can be used as an abrasive and as a diamond simulant and semiconductor of gem-quality as well. The simplest process to manufacture the silicon carbide is to combine carbon and silica sand in electric resistance of an Acheson graphite furnace at a high temperature, raging from 1,600 °C (2,910 °F) and 2,500 °C (4,530 °F).

Silicon carbide (SiC) products are ideal for applications where improvements in efficiency, reliability, and thermal management are desired. Silicon Carbide also has the resistivity necessary to perform as a semiconductor material. Because of these properties, Silicon Carbide is used in a wide range of applications and industries.

Silicon carbide’s unique atomic structure gives it semiconductor properties which are used extensively in the electronics industry. Unlike conductors, which constantly permit the flow of electricity, semiconductors allow their conductivity to be controlled via stimulation by electric currents, electromagnetic fields, or even light.

This all raises a very important question: why silicon? Why is Silicon Used? Silicon is used for electronic devices because it is an element with very special properties. One of it’s most important properties is that it is a semiconductor. This means that it conducts electricity under some conditions and acts as an insulator under others.
