A method was worked out for determining the electric conductivity of watersaturated porcelain mixture in the course of electric resistance drying. On the basis of measuring the starting currents in bodies of various moisture contents, the electric conductivity of mixtures in open and isolated systems can be expressed for a given voltage. The conductivity was found to be independent of moisture content but was affected by the measuring temperature. |
