Improved properties in Dy3+ substituted barium titanate

ABSTRACTIn this paper, effect of Dy3+ substitution on structural, microstructural, dielectric, ferroelectric and piezoelectric properties of barium titanate has been studied. Results of density measurement indicates that substitution of Dy3+ results in increase in density of BT. Grain size increases significantly with the substitution of Dy3+. Dy3+ substituted BT sample possess higher dielectric constant, better ferroelectric properties but weak piezoelectric properties.
