The rheological characteristics of sol solution have been studied. It turns out that the relation of viscosity with temperature can be expressed by the relation μ=μ〓exp , and that the solution's rheological characteristics during the sol—gel transiton are as follows: at first the dilatant fluid changes to Newton fluid, then to pseudoplastic, and finally to gel.
