Abstract
Thermophysical property measurement apparatus and method that can obtain accurate absolute thermoelectric power and thermal conductivity are provided easily and conveniently. A thermophysical property measurement apparatusis provided which includes a DC-AC voltage generatorwhich selectively applies AC or DC voltages of different polarities to a metal sampleto which temperature gradient is provided by connecting the metal samplebetween metal blocks of temperatures Tand T; a thermocouplewhich measures a temperature change at the center of the metal samplewhen the AC voltage is applied thereto by the DC-AC voltage generatorand a temperature change at the center of the metal samplewhen the DC voltages of the different polarities are applied; and an operation devicewhich calculates absolute thermoelectric power and thermal conductivity of the metal sampleusing the two temperature changes measured by the thermocouple
