Spinel sludge samples of different age were prepared by allowing spinel to settle in alumina crucibles. During the aging
process the concentration of spinel crystals increased, which resulted in higher viscosity of the sludge. To quantify this
process, we suggested functions describing dependence of sludge viscosity on spinel concentration, time dependence of spinel
concentration in the sludge, and the dependence of sludge viscosity on sludge age. |
