Influence Of Precursor Dispersity And Agglomeration On Mechanical Characteristics Of Zro2-Ce2O3 And Zro2-Y2O3-Ce2O3 Ceramics

Abstract

Powder precursors of ZrO2 - Ce2O3 and ZrO2- Y2O3 - Ce2P3 systems were synthesized by sol-gel method. Dispersity of the powders depended on concentrations of starting reagents and synthesis conditions. To characterize the powder dispersity and aggregated state, electron microscopy and laser scattering particle size distribution analysis were used. Ceramic samples were prepared from these powder precursors; their mechanical characteristics were studied by three points bending method at 1000°C. It was revealed that bending strength - particle size curve for ZrO2- Ce2O3 system has a pronounced maximum. This phenomenon is explained by a change in cerium valence depending on powder precursor agglomerate size. © 2007 Advanced Study Center Co. Ltd.
