Poly aluminium chloride is an inorganic high-molecule polymer with some cementitious property. It can be used as the binder of refractory coating, ultra-pure alumina products and refractory concrete material. Poly aluminium chloride is a multivalent, polyhydroxy electrolyte and can be seen as the intermediate product of the hydrolysis of AlCl3 into Al (OH) 3. The colloidal nucleus contains positive charge with the hydrolysis product being acidic. The composition of these products is the mixed system of various kinds of aqueous complexes in certain ratio under certain conditions. Its expression formula is [Al2 (OH) n ? Cl6-n] m, wherein n = 1-5, m≤10. Owing to the difference in the preparation and performance, Poly aluminium chloride can also be called as hydroxy aluminum chloride, basic aluminum chloride, and polymeric alumina. The main index of physical and chemical properties includes alkalinity, pH value, Al2O3 content and the relative density. Poly aluminium chloride is rich in raw materials and has low cost without causing decrease of the refractoriness of refractory concrete. It also has strong activity at high temperatures and can be hardened at room temperature when doped with small quantities of accelerators and thus is promising cement material.
