Preparation, microstructure and properties of ceramic composite based on stabilized zirconium oxide

Abstract

A pore-free ceramic composite [88ZrO2-11CeO2-Y2O3]/La0.85Y0.15Al11O18/Al2O3 with a matrix based on zirconium dioxide stabilized with cerium and yttrium oxides, filled with layered particles of lanthanum hexaaluminate and reinforced with aluminum oxide nanofibers, was obtained. The components of the composite were synthesized by the sol-gel method, with the exception of aluminum nanofibers obtained by electric explosion. The phase composition, microstructure and properties of the composite were studied depending on the combined influence of stabilizing additives and aluminum oxide nanofibers obtained by different methods. The composite is intended to be used as a ceramic material for structural and instrumental purposes.
