Silicon carbide, mainly consisting of SiC, it maintains strength up to 1400°C and it is ideal for use as a construction material. SiC has excellent thermal conductivity, low thermal expansion and is very resistant to acids and lyes. It masters corrosion, abrasion and erosion as skillfully as it stands up to frictional wear.
