SILICON CARBIDE IS AN EXTREMELY
HARD CERAMIC MATERIAL

SILICON CARBIDE CERAMIC

 

Materials based on silicon carbide (SiC, also called silicon carbide) have only recently been discovered as materials for mechanical engineering and energy technology. Silicon carbide is the lightest (its density is between 2.6 and 3.2 g/cm³ depending on the porosity), but also the very hardest ceramic material. It is often called "almost like a diamond", and rightly so. Its hardness can be 9.6 according to the Mohs scale (approx. 2600 HV).

 

Ceramics based on silicon carbide have outstanding properties. These include good strength and a high modulus of elasticity of 380 to 430 GPa. They have high thermal conductivity of 120 to 200 W/mK (twice that of steel at room temperature) and low thermal expansion of 3.6 to 4.1x10-6/K (at 20 to 400°C) and therefore has a solid resistance to temperature changes. Silicon carbide ceramic can be used up to 1400°C. In addition, this ceramic has very good corrosion resistance and semiconductor properties.

SILICON CARBIDE / SIC

Light and yet extremely stable – that is what characterizes silicon carbide. Also known as silicon carbide or silicon carbide, the ceramic material shows excellent properties for a wide variety of applications. Components made of silicon carbide are ideal for applications in which wear resistance, high rigidity, corrosion and temperature resistance are of essential importance.
