Premium material: silicon nitride

Why silicon nitride?

Next to carbide, ceramic is one of the most important materials: it is applied when conventional materials are not able to achieve the necessary performance. Characterised by its low density, ceramic demonstrates mechanic stability and also has low thermal conductivity properties. Silicon nitride, in particular, also convincingly demonstrates its high resistance to thermal shock.
