Title: Analysis of dielectric material
Inventor: YANO KATSUMI
IPC: G01R27/00
Filed: 1987-10-24
Abstract: PURPOSE:To measure a fundamental physical quantity a polar molecule or polar group has, by a method wherein a dielectric material is frozen in orientation polarization with a high electric field applied thereto and then, heated up to measure a heat stimulation current and an electric field emission associated with a deoriented polarization. CONSTITUTION:Under such a condition of above specified temperature that permits orientation of almost all of permanent bipoles in the direction of an electric field by applying a high electric field, a high electric field is applied to a dielectric body to achieve an orientation polarization of the permanent bipoles. With the electric field being applied, the dielectric material is cooled below a freezing temperature in the orientation polarization and then, the application of the high electric field is removed. Then, employing a method of deflected reflection or transmission, an infrared spectroscopic analysis is performed quickly. Then, as the temperature of the dielectric material rises at a fixed rate, deoriented polarization is caused sequentially according to the type of the permanent bipole. The infrared spectroscopic analysis is performed quickly again at such a temperature as to maximize a value of heat stimulation current. Such a series of operations is repeated at a varied temperature- rising rate thereby specifying a molecule or a group pertaining to the orientation polarization and the deoriented polarization.
