Silicon Dioxide an overview | ScienceDirect Topics
The reactive silica is called silicon dioxide, and in this form is generally not ionised at normal pH levels of water. 30 The colloidal species is either polymerised silicon with multiple units of silicon dioxide, or silicon that has formed loose bonds with organic compounds or other complex inorganic compounds such as calcium oxide and aluminium silicate. Well waters contain the most silica, from 50 to 100 mg/l.
