“…The extensive use of structural ceramics in the turbine engineering sphere was barred byits inability to withstand tensile loads and large temperature swings. The method of electroconsolidation realized the production of bulk samples of nanoceramics with a density of up to 99% of the theoretical [8]. Most of the samples are characterized by a heterogeneous structure, and the addition of metastable Al 2 O 3 nanopowders causes resistance to high temperatures and has an effect on grain size reduction, which makes it possible to use these materials as elements of new generation gas turbine engine designs.…”

Nanostructured ceramic materials and compositions based on them find an increasing application in all branches of science and technology. At the same time, the performance properties of new ceramic nanomaterials (strength, adhesion, optical and others) are significantly different from properties of traditional ceramics, which were used before. The qualitative characteristics of nanoceramics are largely determined by the initial structure and methods of nanopowder synthesis, as well as by the characteristics of conditions and methods for their consolidation. This work is devoted to the synthesis of nanopowders and effective method of its sintering for the production of nanoceramic materials which have special mechanical properties, e.g. components with increased modulus of elasticity ("ceramic steel"), etc. It makes it possible to effectively use them in aerospace industry.
