According to the material classification system for ceramics, silicon carbide ceramic forms part of the group of non-oxide ceramics. Two types are available:
– The base materials are high-grade silicon carbide raw materials, silicon dioxide (SiO2), and aluminium oxide
– Special quality through a silicon nitride compound (Si3N4)
SiC granules are mixed with temporary and permanent bonding agents. They are manufactured in a dry, semi-dry, or compression process. Formpieces are shaped by casting, followed by a sintering process.
Characteristics:
– Excellent resistance to temperature fluctuations
– High temperature resistance
– High degree of hardness
– High thermal conductivity
– Corrosion resistance
– Max. service temperature limit, depending on the quality, up to 1.700°C
