摘要：

A compound material 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 values of the activation energy for the formation of ZrO2 polymorphic modifications, the size of the crystallites of the compound material matrix were determined; the phase formation and the crystallinity degree of the phases formed in the ZrO2(CeO2,Y2O3)-La0.85Y0.15Al11O18-Al2O3 system were studied in relation to the joint introduction of stabilizing additives and Al2O3 nanofibers.
