Uses:
Locron P 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.
Locron P can be taken as the intermediate of the hydrolysis process of AlCl3 into Al(OH)3 and therefore the hydrolysis solution is acidic.

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 Locron P 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.
Locron P can be used for non-firing or fired to generate refractory products, fire-resistant plastic, and the binding agent of ramming and casting.
When being used as the binding agent of monolithic refractory, it has certain requirement on both the alkalinity and density with Locron P with either too low or too high bond strength not good.
In general, Locron P with alkalized degree being within 46% to 72% and the density being within 1.17~1.23kg/m3 has a good binding strength.
When used as the binding agent of refractory casting, it can be used for synthesizing Magnesium aluminium spinel, electronic melting MgO and as the coagulation accelerator of cement.
But when applying the poly aluminium chloride as unshaped refractory binder, because of its acidic solution (pH <5), it will have reaction with iron and iron-containing compounds contained in the refractory to release hydrogen and cause swelling of the material.
Therefore, the preparation technology should contain aging step in order to avoid the swelling and further cracking of good molded product or lining.
