Abstract :
Precursor powders of a modified lead titanate composition were synthesized using two different chemical routes. The influence of chemical processing on the sintered density, phase composition and dielectric and piezoelectric properties of the powders is described. Both gel-processing and chemical co-precipitation techniques were used to produce the precursor powders. A comparison is made between powders and products made by conventional attribution milling of oxide or carbonate raw materials and those made through chemical processing
