A method has been suggested for studying water transfer in saturated ceramic mix resulting from temperature gradient, and conditions for reliable determination of the thermodiffusion coefficient have been established. The thermodiffusion coefficient value was determined experimentally for one mean temperature; it was found that at small temperature gradients the effect of thermodiffusion on water transfer in a saturated ceramic mix, having a saturated boundary, can be neglected. |
