Grain landscape and dielectric properties of ceramics based on sodium, calcium, strontium niobates, depending on the synthesis and sintering conditions, and mechanical processing

The properties studying results of ceramics based on strontium, calcium and sodium niobates, which vary from the conditions of synthesis, sintering, and mechanical processing, are presented. The evolution of the grain structure of objects is traced depending on their phase filling during concentration changes in the composition and thermodynamic prehistory (preparation conditions).
