Aluminum chlorohydrate CAS 1327-41-9

Specification

Application

It is one kind of refractory binder. It is a kind of aluminum hydroxide sol made from aluminum-containing material or aluminum metal which subject to several chemical/physical treatment steps such as hydrochloric acid dissolution, hydrolysis, and polymerization. Poly aluminium chloride can be taken as the intermediate of the hydrolysis process of AlCl3 into Al(OH)3 and therefore the hydrolysis solution is acidic. Poly aluminium chloride is also known as hydroxy aluminum or basic aluminum chloride with the chemical formula being [Al2 (OH) nCl6-n] m, wherein if the n is close to or equal to 6, it can be called as alumina sol. Applying poly aluminium chloride as a binding agent of loose refractory will not affect its refractoriness. The Al2O3 generated during the dehydration and decomposition of poly aluminium chloride during the heating process is a kind of active alumina oxide with high-degree of dispersion which can facilitate the sintering, and thus being suitable for being used as the refractory binder.
