Special techniques
Thermoelectric measuring device (self-made IPF) for the measurement of the temperature-dependent Seebeck coefficients, the electrical conductivity, the power factors and the figure of merit.
Powder conductivity measuring device (self-made IPF) for the measurement of the pressure-dependent electrical conductivity of powders and pastes (pressure up to max. 30 MPa)
Adjustable temperature measuring device (self-made IPF) for measurement of the directional electrical conductivity
GNOMIX PVT apparatus (GNOMIX Inc,USA) to determine changes in the specific volume of solids and liquids depending on pressure (0.1 MPa to 200 MPa), temperature (RT - 400 °C) and time (t → ∞)- Phase state equations- Phase transitions- Chemical changes
