sodium metasilicate effect on silicate ores

PQ Sodium Silicates Geopolymer

sodium silicate adds no phosphate or zinc to the water supply. Also, when compared to phosphatebased corrosion inhibitors, sodium silicates have a beneficial effect on pH. Added in the proper amount, sodium silicate can raise system pH into the alkaline range – another EPArecommended way to lower lead levels in a municipal water system.
