Abstract :
Piezoelectric (Pb0.5Bi0.5)(Ti0.5(Fe1-xMn x)0.5)O3 (x=0.00-0.02) ceramic powder was prepared by alcohol dehydration of an aqueous multicomponent ammonium citrate solution. The tetragonal phase with the desired stoichiometry formed after heat treatment at as low as 800°C. A high tetragonality (c/a ratio of 1.140±0.001) was achieved after heat treatment at 1000°C for 1 h. Flexible 0.3 composites prepared from the 1000°C powder (x=0.01) and Eccogel polymer exhibited piezoelectric charge coefficients (d 33) of 60 pC/N and a voltage coefficients (g33 ) of 205×10-3 Vm/N
