Extract

Ceramics based on silicon nitride have long been considered promising candidates for high temperature engineering applications due to their excellent refractory properties combined with high strength and good resistance to oxidation. It is well known, however, that the performance of ceramics varies considerably with chemical composition, for example with type and amount of intergranular phase. Especially the evaluation of the high temperature behaviour of the ceramics under varying conditions is therefore important in increasing the knowledge of these materials.
