Manufacturing and characterisations of hafnia-based materials for aerospace applications

Résumé

Considering more severe operating conditions in combustion chambers, new systems of materials are developed by CNES, ONERA and ICB. In the present study, stabilised hafnia has been chosen for the ceramic part of this system as its thermophysical properties are interesting compared to other ceramics. More precisely, hafnia based materials with different natures (Lu2O3, Y2O3 and Gd2O3) and amounts of stabilisers have been manufactured using a solid state reaction. Fully stabilised materials were obtained and the microstructures and the thermal expansion coefficients up to 1550°C were investigated.
