Abstract

Abstract Pyroelectric, dielectric and other properties have been measured on naturally occurring hemimorphite Zn 2Si 2O 7(OH) 2·H 2O Crystals. Hemimorphite has a strong pyroelectric coefficient (−45 μC/m 2°C at room temperature), low permittivity and loss, and weak piezoelectricity, making it an appealing sensor material. Dehydrated hemimorphite is also polar, and selected properties of this material are presented.
