Silica Precipitation in Acidic Solutions: Mechanism, pH .

This study is the first to show that silica precipitation under very acidic conditions ([HCl] = 2−8 M) proceeds through two distinct steps. First, the monomeric form of silica is quickly depleted from solution as it polymerizes to form primary particles ∼5 nm in diameter. Second, the primary particles formed then flocculate. A modified Smoluchowski equation that incorporates a geometric ...
