Product Name:Aluminum silicate
English Name:Aluminum silicate
CAS No.:12141-46-7
Aliases:Aluminosilicate, Aluminum metasilicate, Anhydrous aluminum silicate
Molecular Formula:Al2O5Si
Physical Properties:White amorphous powder, odorless and tasteless, insoluble in water, ethanol and acetone, slightly soluble in hydrochloric acid, with strong adsorption capacity and chemical stability. Density approx. 2.6 g/cm³, melting point approx. 1800°C (decomposition), high refractoriness, low thermal expansion coefficient.
