Abstract

Searching for materials with good piezoelectric properties above 150 °C, special attention has been given to the family of ferroelectrics compounds of bismuth with laminar structure. We report the processing of a ceramic form of a member of such family, namely the PbBi4Ti4Nb0.06O15,15. Following the conventional method, we mixed PbBi4Ti4O15 (PBIT) and niobium oxide. We have studied the crystal structure and the microstructure of the sinterized material at several temperatures. The structural characterization suggest that the PBIT doped with niobium is the only phase present with orthorrombic simetry. The microstructure shows plaque – like grains smaller than the ones in PBIT.
