PbCa2TiNb2O6

PbCa2TiNb2O6 is a perovskite oxide with the general formula ABX3. In this specific compound, lead (Pb) and calcium (Ca) occupy the A-sites, titanium (Ti) and niobium (Nb) occupy the B-sites, and oxygen (O) occupies the X-sites. The structure is based on a cubic perovskite lattice.

This material belongs to the family of complex perovskites, which are known for their diverse electrical and dielectric properties. The presence of multiple cations in the A and B sites can lead to interesting phenomena such as relaxor ferroelectricity and high dielectric permittivity.

Research on PbCa2TiNb2O6 has focused on its potential applications in electronic devices, particularly as a dielectric material in capacitors due to its potential for high capacitance density. The specific arrangement of Ti and Nb on the B-site, along with the mixture of Pb and Ca on the A-site, influences the material's phase transitions and dielectric behavior. Synthesis methods often involve solid-state reactions at elevated temperatures.

Further investigation into the precise crystal structure, phase stability, and dielectric properties as a function of composition and processing conditions is ongoing to optimize its performance for specific technological uses.
