GEOMETRIC FACTOR FOR CONVERSION OF ELECTRICAL RESISTANCE INTO RESISTIVITY
Rudolf Podoba, Igor Štubňa · 2012
The contribution describes an experimental determination of the geometric factor k which transforms measured resistance R into resistivity raccording to formula r = R / k. The factor should be used for a new electrode-sample system designed for conductometric thermal analysis of the green ceramic materials. As our experiments showed, the factor is very sensitive for location of the wire electrodes in the sample. For the investigated electrode-sample system k = 12,88m-1.
