Simultaneous Determination of Seebeck Coefficient and Electrical Conductivity
In order to be deemed suitable, thermoelectric materials should be characterized by high Electrical Conductivity (SBA)Electrical conductivity is a physical property indicating a material's ability to allow the transport of an electric charge.electrical conductivity, a large Seebeck coefficient and low Thermal ConductivityThermal conductivity (λ with the unit W/(m•K)) describes the transport of energy – in the form of heat – through a body of mass as the result of a temperature gradient (see fig. 1). According to the second law of thermodynamics, heat always flows in the direction of the lower temperature.thermal conductivity. The extent to which it will be possible to use thermoelectric generators in the future will depend upon the performance of the materials.
Instruments for the determination of thermal conductivity, Thermal DiffusivityThermal diffusivity (a with the unit mm2/s) is a material-specific property for characterizing unsteady heat conduction. This value describes how quickly a material reacts to a change in temperature.thermal diffusivity, cp determination and DensityThe mass density is defined as the ratio between mass and volume. density are also included in the NETZSCH product range. NETZSCH thus offers a complete solution for determining the ZT value.
