This paper discusses use of the plasma dynamic synthesis to obtain ZnO-Bi2O3 composite powder. This method allows to get the main ZnO material with the formation of core-shell particles. Sintering of ceramics from this material was carried out using spark plasma sintering facility. Use of this sintering method provides obtaining a fine-grained structure of ZnO (average grain size of 1.3 μm). Comparison of the current-voltage characteristics of ceramics from commercial and plasma dynamic materials showed promise of using a ZnO- Bi2O3 composite with a core-shell structure.
