BCZT is a promising lead-free ceramic material with superior electrical properties, exhibiting morphotropic and polymorphic phase transitions that contribute to its exceptional piezoelectric and ferroelectric properties. It has a high piezoelectric constant and large remnant polarization, along with a high Curie temperature, making it fascinating for use in the electrical world. The study examines the effect of doping on the modification of electrical properties through changes in phase transition temperature, structural modification, and bulk formation.
Barium calcium zirconate titanate (BCZT) is one of the most promising lead-free ceramic materials due to its superior electrical properties. BCZT exhibits the existence of morphotropic phase transition (MPB) and polymorphic phase transition (PPT) that are considered as the basis for superior piezoelectric and ferroelectric properties. It also exhibits a high piezoelectric constant (d33 similar to 620pC/N) and a large remnant polarization (Pr similar to 17.mu C cm(-2)). Due to the presence of a triple point, it also exhibits a high Curie temperature (T-C). These properties make BCZT a fascinating lead-free ceramic material for use in the electrical world. Here, we have studied the effect of doping on the modification of ferroelectric, dielectric, and piezoelectric properties. The modification of electrical properties caused by the change in phase transition temperature, and by structural modification and bulk formation are discussed.
