Sodium Orthosilicate

SODIUM ORTHOSILICATE (Tetrasodium silicate) has been considered as an interfacial tension reducing additive in the water flooding of oil fields for enhanced oil extraction. In laboratory settings, it was found to be more effective than sodium hydroxide for some types of oil. Sodium Orthosilicate has been found to stabilize ferrate films as an anticorrosion treatment of iron and steel surfaces.  It is offered in Technical Grade and chemical Grade. It is available in the form white crystals packed in 25kg, 50kg HDPE Bag. We can offer it in many grades as per the application needs in different industry sectors.
