What is Activated Silica? - Definition from Corrosionpedia

Aug 07, 2014 · The activation reaction is believed to be the neutralization of sodium silicate, leading to polymerization of silicate ions. The process acidifies the silicate and uses caustic material to raise the pH to less than 12 to stabilize the activated silica. The applications of activated silica depend mainly on the size, charge and shape of the polymer.
