Sintered silicon carbide is created when pre-pressed and very soft SiC granulate is sintered at a temperature of more than 2,000 °C, when very strong sintering bonds between the material grains are formed. Firstly, there is lattice densiﬁ ion, then the porosity is lowered, and ﬁ nally, sintering bonds between the grains of SiC are formed.

Silicon Carbide is among the hardest of ceramics, and retains hardness and strength at elevated temperatures, which translates into among the best wear resistance also. Additionally, SiC has a high thermal conductivity, especially in the CVD (chemical vapor deposition) grade, which aids in thermal shock resistance. It is also half the weight of steel.
Silicon carbide – a solid with covalent bonds - is conventionally synthesized via the Acheson process. Usually solid bodies of silicon carbide with definite shapes are generated from the grained material via hot isostatic pressing or liquid phase sintering. Both processes are conducted under well-controlled temperature regimes.
