Abstract
Ferroelectric barium strontium titanate (BST) glass-ceramics doped with different content of La2O3 were prepared via the melt-quenching technique followed by controlled crystallization. The microstructures of crystallized samples were examined by X-ray diffraction and scanning electron microscopy. Dielectric properties were also investigated. The aliovalent substitution of Ba by La induced dispersion of semiconducting BaxSr1âxTiO3 crystallites sealed in a glassy silicate matrix, which increased the εr and loss tangent values of the BST glass-ceramic. The experimental results indicate that aliovalent substitution is an effective method to process glass-ceramics with better dielectric properties.
