Phase Transitions in New Lead-Free BiLi_0.5Sb_0.5O₃ Ceramics

Abstract

Physical properties of new ferroic BiLi_0.5Sb_0.5O₃ ceramic material have been studied by dielectric, mechanical, and thermal spectroscopy methods. The experimental data revealed two structural phase transitions in BiLi_0.5Sb_0.5O₃ ceramics near 50 and 220°C.

Keywords:

• Lead-free ceramics
• phase transition
• dielectric permittivity
• internal friction
• shear modulus
