摘要:A review of advances on solubility of amorphous silica in aqueous solutions has been made. Relevant literature on effects of temperature, pH, pressure and dissolved salt content on silica solubility has been discussed. Also reviewed is the research work on polymerization of amorphous silica over a range of pH, temperature, supersaturation and salinity conditions. The existing models for the polymerization rate are summarized and compared. The reports on reaction order and maximum polymerization rate have been contradictory. Lack of solubility and polymerization data at elevated temperature, pH and, especially, in solutions containing multi-component dissolved salts are found to limit advances in current understanding of silica behavior.
