Characteristics of the (Ba1-xPbx)TiO3 Powders Prepared by Various Synthesis Method

ABSTRACT

Characteristics of the sol-gel derived (Ba1-xPbx)TiO3 powders are compared with those of powders prepared by the calcining ofmixed oxides method (CMO) and molten salt synthesis method(MSS). The sol-gel derived powder has a higher surface area (50$m^2$/g) than those of CMO(3.8$m^2$/g) and MSS(11.5$m^2$/g) derived powders. In the sol-gel method, the (Ba1-xPbx)TiO3 was synthesized at $600^{circ}C$ for 1hr, indicating that this method has a crystalline temperature 20$0^{circ}C$-30$0^{circ}C$ lowr than those of the CMO and MSS methods.
