Effects of rare earth additive (Nd2O3) on microstructure and dielectric properties of lead zirconate titanate ceramics

This paper presents work on studying the structure and physical properties of PZT ceramics at a morphotropic phase boundary composition (Zr : Ti=52 : 48) which has been modified with different quantities of neodymium oxide, Nd 2O3. Phase formation and microstructure development were examined by x-ra...
