Structural Characterization of Orthorhombic and Rhombohedral Lead Meta-Niobate Samples

The meta-stable orthorhombic phase of lead meta-niobate (PbNb 2 O 6 ), as obtained by quenching, is piezoelectric, but difficult to prepare in pure state as a few competing phases like the non-piezoelectric rhombohedral PbNb 2 O 6 tend to form during the preparation. However, it can have an attracti...

Description
Summary:The meta-stable orthorhombic phase of lead meta-niobate (PbNb 2 O 6 ), as obtained by quenching, is piezoelectric, but difficult to prepare in pure state as a few competing phases like the non-piezoelectric rhombohedral PbNb 2 O 6 tend to form during the preparation. However, it can have an attractively high Curie temperature above 570°C. High Curie temperature piezoelectric sensors are desirable for imaging and other applications in certain industrial and research sectors. Presently, both phases have been synthesized as single phase samples as shown here from structural Rietveld analysis of their XRD. Characterization of both compounds by FTIR and XRD have been carried out and presented.
