The new phenomena that results in an increase of the strength of zirconium-containing ceramics under the action of ion-plasma treatment of the initial powders is detected. The effect of the ion-plasma treatment of the ZrO2 powders on the mechanical properties of ceramics is studied. The irradiation of the zirconium dioxide powders with low-energy Tl+ ions results in an increase of the strength of zirconium-containing ceramics by 30%. The ion modification of the ceramics based on the mixed ZrO2-Al2O3 oxides results in an increase of its bending strength and in an increase of the fracture toughness by 15-20%. The effect is independent of the nature of accelerated ions and the initial strength of the samples.
