The basis of silicon nitride ceramics

In aerospace applications, good resistance and rigidity under high temperatures, as well as low weight and low thermal expansion, are particularly important – all of which are properties found in structural components made of Silicon nitride. This makes the ceramic of interest for, among other things, housings of reconnaissance and observation cameras and for support structures of satellites. The advantage here is that the low thermal expansion, even in the case of extreme temperature fluctuatio
