IMPROVED METHODS FOR REMOVAL OF SILICATE

2018-2-13  There are two generally accepted chemistries used for silica dissolution. The first, and the one most often used in chemical cleaning, is HF (hydrofluoric acid); either in the form of pure HF, or as fluoroboric acid, or created in situ by combining HCl with ammonium bifluoride (ABF). The second method is to react with strong alkali – NaOH or KOH. This is more typically used in industrial settings for the
