Products Description of LITHIUM METASILICATE CAS#10102-24-6Lithium silicate is a kind of water-soluble silicate. It is an odorless, tasteless transparent liquid. It is soluble in water and alkaline solutions, but insoluble in alcohols and organic solvents. Since the radius of lithium ions is much smaller than that of sodium and potassium ions, lithium silicate aqueous solution has some unique properties. It reacts chemically with acid like sodium water glass to form dioxide gel.
