Contact resistivity cell
This cell can be used at (approximately) room temperature and under atmospheric pressure conditions to measure the electric resistivity of a pressure dissolving, annular contact between a glass lens and a salt crystal. At the same time, the growing contact can be directly observed through the glass lens. This cell has been used for example in the investigation of the structural and diffusional properties of grain boundaries under stress.
Pressurised conductivity cell
This cell is submerged in an oil bath and the temperature may be controlled to approximately 0.1 °C. Impedance spectroscopy with this cell can be done by use of a Solartron 1260A frequency response analyzer and 1296 dielectric interface. This cell is used for impedance spectroscopy on loaded powders with pore fluid and has recently been used on coal samples.
