摘要: Polycrystalline samples of lanthanum modified bismuth titanate ceramics with composition Bi3?25La0?75Ti3O12 (BLT) were prepared at three different sintering temperatures (1050, 1100 and 1150uC) using M-PVA gel ignition technique. The characterised for structural electrical properties. A significant amount as burnt BLT powder was found to be crystalline in nature having a yellowish colour. Very fine nanoparticles by TEM analysis. Single phase orthorhombic crystal structure observed all the samples, confirmed X-ray Dielectric properties studied function frequency temperature. More than 95% relative density sintered samples. sample 1100uC showed highest dielectric constant lowest loss.
