Electrical Resistivity Measurement of the Molten Cordierite Glass Using Two-wire method

Electrical resistivity (ER) is a main parameter in the melting processes of glasses. However, its measurement is difficult at high temperatures. In this study the electrical resistivity of different cordierite glass samples in the molten state was measured in the temperature range of 1100˚C to 1550 ˚C using the two-wire method. It was attempted to decrease the electrical resistivity of the glas...

A Method of Measuring Earth Resistivity

A knowledge of earth resistivity ^ (or specific resistance) maybe of value in determining something of the composition of earth, such for example, as moisture content, whether it contains oil, ore of high conductivity, etc., or in the calculation or mitigation of damages to pipe systems by electrolysis caused by the rettim current of street-railway systems. For some of these or other reasons we...

Stability analysis of apparent resistivity measurement in the seismically active area of Val d'Agri (southern Italy)

A magnetotelluric monitoring station has been installed in the Val d’Agri area (southern Italy), to investigate the physics underlying the generation mechanisms of the electrokinetic effect, due to rapid pore pressure changes and fluid flows near the focal area of incoming earthquakes. It is well known that the magnetotelluric method reveals variations in electrical resistivity within the Earth...

High Resistivity Measurement of SiC Wafers Using Different Techniques

To establish fast, nondestructive, and inexpensive methods for resistivity measurements of SiC wafers, different resistivity-measurement techniques were tested for characterization of semi-insulating SiC wafers, namely, the four-point probe method with removable graphite contacts, the van der Pauw method with annealed metal and diffused contacts, the current-voltage (I-V) technique, and the con...
