Dear Colleagues, Silicon carbide is the only binary compound of silicon and carbon that exists in the solid phase under normal conditions. As early as 1824, Jöns Jakob Berzelius first suggested that a chemical bond might exist between silicon and carbon. Silicon
Reaction bonded silicon carbide is a multi-phased material typically containing 7-15% silicon metal, some minor amount of unreacted carbon, with the remaining body being SiC. Reaction bonded SiC materials are manufactured utilizing a variety of processes depending on desired final product geometry, configuration, and required tolerances.
