Solid-State Mechanochemical Syntheses of Perovskites

Abstract

The chapter presents the possibility of applying high-energy ball milling techniques to car‐ ry out the synthesis of ceramics with perovskite structure, thereby eliminating prolonged use of high temperatures in their preparation. On the examples of alkaline-earth metal perovskites, an influence of the most significant parameters of mechanochemical treatment on their forming process and product quality was illustrated. For the first time, it was done that the contamination of the product de‐ rived from the attrition of the grinding media and internal parts of the vial can constitute modifiers of the functional properties of produced electroceramics. Dielectric characteristics of mechanochemically produced materials as well as using high- temperature solid synthesis were compared.
