Recently, the Chief Minister of Odisha performed the groundbreaking ceremony for the country’s first end-to-end silicon carbide semiconductor production plant.
About Silicon Carbide:
It is a synthetically produced crystalline compound of silicon and carbon.
Its chemical formula is SiC and it is the most widely used non-oxide ceramic.
It was discovered by the American inventor Edward G. Acheson in 1891.
Properties of Silicon Carbide
Hardness: It is the hardest ceramic material and has excellent thermal conductivity, low thermal expansion.
Conductivity: It is also classed as a semiconductor, having an electrical conductivity between that of metals and insulating materials.
It has excellent mechanical properties, and excellent resistance to wear and oxidation.
Applications of Silicon Carbide
Abrasives: Its primary application is as an abrasive because of its high hardness, which is surpassed only by diamond, cubic boron nitride, and boron carbide.
Refractory linings: It is used in refractory linings and heating elements for industrial furnaces, in wear-resistant parts for pumps and rocket engines.
Semiconducting substrates: It is used in semiconducting substrates for light-emitting diodes.
It is a promising ceramic material with excellent thermo mechanical characteristics.
