Sodium metasilicate Sodium metasilicate is a chemical substance with the formula Na 2SiO3, which is the main component of commercial sodium silicate solutions. It is an ionic compound consisting of sodium cations Na+ and the polymeric metasilicate anions [ SiO2 3 ]n. It is a colorless crystalline hygroscopic and deliquescent solid, soluble in water (giving an alkaline solution) but not in alcohols
