Abstract

Hard porcelain samples were prepared with and without the addition of mineralizers. The concentrations of mullite, quartz and glass phases and the size as well as size-distribution of mullite crystals in the samples were determined by XRD and TEM. The electrical resistivity of the samples was measured from room temperature to 900-degrees-C and the influence of mullite and glass on the resistivity was studied. The thermal activation energy of the electrical resistivity of samples was calculated and it was shown by statistical analysis that only the concentrations of mullite and glass have a very significant effect on the electrical resistivity of the samples, the effect of mullite being opposite to that of Glass.
