Nitride Bonded Silicon Carbide (NBSC)

Mar 06, 2001· High-density silicon carbide materials are manufactured by adding a sintering aid that creates a second bonding phase. Most often, the thermomechanical properties are restricted by the bond phase. For instance, the highest operating temperature of reaction bonded silicon carbide is 1375 °C, which is close to the silicon’s melting point.

Silicon Ntride

The bonding around the nitrogen atoms is therefore somewhat sp 2-like: that is, three hybrids of s, p x and p y form three bonds to silicon atoms, with the p z orbitals (sticking out of the plane) non-bonding. The detailed structure of the crystalline forms of silicon nitride is known but is very complex.
