Sodium silicoaluminate 2381409 209643020 2008-05-02T06:34:45Z Zywxn 5471802 '''Sodium aluminosilicate''', also referred to as [[sodium silicoaluminate]], is a chemical with the formula AlNa<sub>12</sub>SiO<sub>5</sub> and [[CAS registry number|CAS]] 1344-00-9. It is an [[aluminosilicate]] [[Compound (chemistry)|compound]] with [[sodium]] cations, taking the form of a white crystalline solid. In [[mineral]]s, as a [[feldspar]], it is found as [[albite]], an end-member of the [[plagioclase]] series with the formula NaAlSi<sub>3</sub>O<sub>8</sub>. It is often added as an [[anticaking agent]] to various products including [[table salt]] and other food products, powders, and house paints to prevent the formation of large [[crystals]] or lumps. When used as a [[food additive]], it is sometimes designated "[[E number|E-554]]". Some other applications of sodium silicates: * For their detergent properties: in silicated soaps, in fabric washing powders, for dishwashers, for cleaning metals, for washing bottles; * For their binding properties: in cardboard and paper making, in the production of refractory and insulating materials, in the timber, fertilizer and welding electrode industries, in casting for sand molding, for ground consolidation, for fire protection; * For removing ink from waste paper, in water treatment, in ore flotation, for production of special cements and of cracking and zeolite catalysts; * As intermediate products in the manufacture of Zeolite A (sodium silicoaluminate). * Also used in some meal replacement shakes. ==Synonyms== Sodium silicoaluminate may also be listed as * Silicic acid, * aluminium sodium salt, * Sodium aluminosilicate, * Aluminosilicic acid, * sodium salt, * Sodium aluminium silicate, * Aluminum sodium silicate * Sodium silico aluminate, or * Sasil; Sometimes "silicoaluminate" is broken into "silico aluminate". ==External links== [[Category:Inorganic compounds]] [[Category:Sodium compounds]] [[Category:Aluminosilicates]] {{Inorganic-compound-stub}} [[hu:Nátrium-alumínium-szilikát]]
