Pyroelectricity in ceramics composite

Abstract

Pyrocomposites comprising pyroelectric ceramic and ceramics/polymer/glass/cement content due to their exceptional and tailorable pyroelectric characteristics. Pyrocomposite has various advantages, such as high pyroelectric coefficient (p) or depolarization (T d)/Curie temperature (T c), low dielectric constant (tanδ), mechanical flexibility, and the ability to design electrodes for arrays. This chapter discusses several composites for pyroelectric ceramics. In this direction, the pyroelectric glass-ceramics composites are initially explained. Numerous types of glass are heat-treated to form ceramic composites or added to the ceramics to create a composite that can improve pyroelectric characteristics. Then, cement-based pyroelectric ceramic composites are examined

these materials may be produced using an inexpensive molding technique that eliminates the need for a sintering step. Moreover, semiconductor, ceramic, and polymer-based composites are studied in detail. Polyvinylidene fluoride (PVDF) polymers are extensively utilized as pyroelectric ceramic polymer composites owing to their excellent flexibility and improved pyroelectric figures of merit. A comprehensive table for each category of pyroelectric composites is given, which provides guidelines for selecting appropriate composite fabrication. © 2026 Elsevier Ltd. All rights reserved.
