ABSTRACT:
In a method for measuring thermo electricity and an apparatus thereof, enabling to measure the physical characteristics including electrification of a sample even in a humid (water-vapor) atmosphere, a sample10of powder to be measured and formed in a predetermined shape is disposed within an inside of an electric furnace30, building up a heating and temperature increasing portion, which is stored within a constant-temperature container of three(3)-layers (51, 52, 53) structure (or may be two(2)-layers structure), forming a measuring chamber50in an inside thereof. While increasing the temperature, a measuring apparatus for detecting the thermal stimulated current (TSC) by means of a minute current detector connected to electrodes, which are provided opposing to the sample10, and there is further provided a water-vapor generating apparatus100for guiding a water-vapor atmosphere at a predetermined value into the measuring chamber50of the constant-temperature container. Further, the temperature of the constant-temperature water supplied from a constant-temperature water supply apparatus into the constant-temperature container is set to be a little bit higher than that of the water-vapor atmosphere supplied from the water-vapor generating apparatus100.
