Advanced Ceramics: Intrinsic and Extrinsic Factors

Abstract

The efficiency of devices based on advanced ceramics is related to the optimization of material properties. In this paper, we discuss the intrinsic and extrinsic factors that influence the properties of advanced ceramics.

Perovskite Structure and Phase Transition Due to Temperature

“…The perovskite structure is organized into 5 symmetries: cubic, tetragonal, orthorhombic, rhombohedral, and monoclinic. Symmetry changes are due to temperature variation, induced polarization or impurities added in the unit cells [3][4][5].…”
