The paper deals with the determination of the diffusion ooefficient of water and its temperature dependence in an open system during the drying of a saturated porcelain mix with an inner electric heat source. The method is based on establishing the time dependence of the moisture oontent in the body and of the moisture profile under quasistationary conditions. In an open system, the effect of an alternating electric current promotes diffusion of water through saturated porcelain mix. |
