“…Moreover, different substituents for lattice sites (Ba and Ti) can be used for tailoring its properties. Isovalent ions (like Zr 4 þ , Sn 4 þ , Mn 4 þ for Ti 4 þ and Pb 2 þ , Sr 2 þ , Ca 2 þ for Ba 2 þ ) and aliovalent ions (like Mn 3 þ , Nb 5 þ , Fe 3 þ for Ti 4 þ and Sm 3 þ ,La 3 þ , Pr 3 þ , Gd 3 þ for Ba 2 þ ) can result in modification of properties making it useful for various applications like MLCC, PTCR, FRAMS, and sensors [3][4][5][6][7][8]. For the present study, a BT-based composition with formula Ba 1 À x Pb x Ti0 .90 Zr 0.10 O 3 (0 rx r0.20, in steps of 0.05) was selected.…”
