ABSTRACT The 0.8Pb(Zr 0.48 Ti 0.52 )O 3 – 0.125Pb(Zn 1/3 Nb 2/3 )O 3 – 0.075Pb(Mn 1/3 Nb 2/3 )O 3 + x wt% Fe 2 O 3 ceramics (PZT-PZN-PMnN), where x = 0 ÷ 0.35, has been prepared by two-stage calcination method. The effect of Fe 2 O 3 content on the crystal structure and electrical properties of ceramics has been investigated. The results of X-ray diffraction (XRD) show that all samples have pure...
