Effects of Milling Technique on Physical and Mechanical Properties of Lead-Free Ba(Zr_0.3Ti_0.7)O₃ Ceramics

Abstract

Barium zirconium titanate powders with a composition of Ba (Zr0.3Ti0.7)O3 were synthesized by a conventional mixed oxide and vibro-milling method. Ba (Zr0.3Ti0.7)O3 ceramics were fabricated from the synthesized powders. The effects of milling technique on the physical and mechanical properties of the prepared samples were investigated. Compared to conventional samples, the samples prepared by the vibro-milling method showed a higher densification. The vibro-milling methods also produce a higher degree of crystallinity. The microstructure results were correlated with the characteristics of the milling process. The measurement results indicated that the milling technique affected both of physical and mechanical properties of the lead-free BZT ceramics.
