Silica in Plants: Biological, Biochemical and Chemical ...

The process to produce silica sol has a history that stretches back to the early 1900s [5]. The rst patent for commercial production of silica sol was announced in 1915, where Schwering used electrodialysis to manufacture a pure and stable sol of 2.4% silica [6]. A stable silica sol to reach a concentration of 10% silica was rst marketed in 1933.
