Regularities of the change in colloid-chemical properties of silica hydrosols in the presence of alkali metal hydroxides

The effect exerted by type of alkaline hydroxide additive on the change in turbidity and on the formation of silica hydrosol spatial structures was studied. Silica depolymerization in an alkaline solution to form active silicic acids was studied depending on the aging time of the system, size of sol...

Summary:The effect exerted by type of alkaline hydroxide additive on the change in turbidity and on the formation of silica hydrosol spatial structures was studied. Silica depolymerization in an alkaline solution to form active silicic acids was studied depending on the aging time of the system, size of sol particles, and the type of alkaline hydroxide additive.
