ABSTRACT:We have studied the influence of a new lead-free Fe/Li incorporated H-Bt prepared by the solid state reaction method and compared it with pure hexagonal barium titanate. The hexagonal phase was stabilised at room temperature due to substitution with Fe-Li. Lattice constants were refined as a = 5.720 A.U., c = 13.96 A.U. Both XRD and IR imply that Li enters octahedral as well as Ba sites. Dielectric measurements show an increase from 800 to 10 5 indicating sample to be potential colossal dielectric constant (CDC) material. Abnormal grain growth (AGG) was restricted in the substituted sample and normal grain growth was observed.
