Abstract |
The report gives results of a study during which 28 fly ash samples--representing a broad spectrum of ash compositions produced by burning coal in commercial power station boilers--were characterized, chemically analyzed, and fabricated into sintered-disc resistivity specimens. Resistivity and transference experiments were performed in the temperature range in which volume conduction prevails. Results confirmed conclusions of an earlier investigation: the volume conduction mechanism for fly ash is ionic; and the charge carriers are the alkali metal ions, principally sodium. Increasing iron concentration caused a resistivity decrease for a given level of sodium and lithium. From these data, empirical equations were developed to predict the volume resistivity of fly ash as a function of ash chemistry, temperature, and porosity. |
