• What is silica

    Colloidal silica consists of dense, amorphous particles of SiO 2 .The building blocks of these particles are randomlydistributed [SiO 4 ]tetrahedra. This random distribution is what makes amorphous silica different from crystalline silica ordered on a molecular level. Sodium silies are alkaline solutions with pH ranges of 1213, compared ...
