Alumo-boron-nitride-based heat-resistant, thermostable, shrinkage-free structural ceramic material was developed and manufactured by vacuum-compression impregnation technology. Actually, all the high-temperature path parts for 2.5 MW gas-turbine engine were made of this ceramic material [1]. The results of the granulometric, microstructural, phase and other characterization into the material are presented. New conditions of interaction between the boron nitride and aluminium were identified.
