Differences between acidic silica sol and alkaline silica sol
Thread Content
Silica sol, also known as an aqueous solution of silica, is a colloidal solution in which particles of hydrated silicon dioxide are dispersed in water. Depending on the pH value it exhibits, silica sol can be divided into basic silica sol and acidic silica sol. They are all important fine chemical products with various important applications: for example, basic silica sol is used in fields such as precision casting and exterior wall coatings ； Acidic silica sols are used in color picture tubes, colloidal lead-acid batteries, as well as in the electrostatic flocking technology introduced from abroad. The main difference between acidic silica sol and alkaline silica sol is their pH value.
