Study on a new type of pyroelectric materials with structure of tourmaline
Source abstract
Abstract
Abstract Pyroelectricity is mainly affected by the structure of materials. To explore the influence of the structure on pyroelectricity, a new type of pyroelectric materials with structure of tourmaline consisting of Li9Mg3[PO4]4F3, Ba3Sr4(BO3)3F5 and tourmaline have been systematically studied in this work. Based on the comparison results of the pyroelectric coefficient of Li9Mg3[PO4]4F3 and Ba3Sr4(BO3)3F5 after heating and the variations of electric dipole moment, it suggests the tetrahedron is less stable than trigon, and is easily to cause the distortion and deformation of structure, which leads to the great enhancement of pyroelectricity. Additionally, it can find that the tetrahedron has the most contribution to the pyroelectricity by comparing the pyroelectric coefficient and total electric dipole moment of Li9Mg3[PO4]4F3, Ba3Sr4(BO3)3F5 and tourmaline which have different polyhedrons.
