Effect of sintering temperature on the structure and strength of ceramics 1Ce10ScSZ

Abstract

The influence of sintering temperature on the structure and mechanical behaviour of ceramic electrolyte with cubic zirconia powders 1Ce10ScSZ of three different types, which differ on composition, distribution of impurities and properties of initial particles and their agglomerates, were made. Consider that the process of consolidation of powders and improve the structure of ceramics by sintering is thermal activity, invented value that set depending on the strength and subgrain/grain size , porosity , quality of grain boundary and sintering temperature. Was founded that activation energy is determined by processes compaction / porosity, grain growth, the state of grain boundary and strengthening / softening with cleavage and intergranular fracture.
