Abstract
The method of calculation of viscocity presented in this paper lead to reasonably accurate value in the co11po1itioo range of O. 3 < X s io2 < l, for binary, ternary and multicomponent systems. The N0°, NO- and H02 - ions distribution in the melts bas been evaluated based on the depolymerization reaction. The N0° values obtained by the atomic pair 11odel agree very well with the experimental data. An equation was derived using the hole theory to express the temperature and dependence of visco1ity. The deduced equation: n - 4.9 X 10-9 t 112 N0° exp(E/RT) (poise) is successfully applied to predict the viscosity of several binary, ternary and multicomponent systems. Excellent agreement between calculated viscosity values and experimental data for several temperature was observed. Viaco1itie11 of industrial spent potlining(SPL) were measured as a function of temperature and with the oxide addition to the SPL. The results showed that the viscosity of SPL decreased with increasing temperature and also decrea1ed with the addition of 20
wt% Cao and 20 wt% s102 to SPL.
