Aluminate Hydroxide

Description

The term Aluminate Hydroxide (Aluminate Gel) indicates a very varied range of colloidal hydroxides: varied by the media: water, solvent or air, varied by the morphology: colloidal particles or coherent and homogenous mass, varied by the structure: amorphous, insufficiently crystallized or advanced in hydroxide, varied by the apparent density, varied by the purity. Their importance comes from their properties. Acid absorbency they play an essential role in geology (chemistry of the soil). Toxicity free, they are used as gastric antacids. Polymorphous in density, particle size and surface, they are the main precursors of catalysts and adsorbents. The gels can be very pure, and so can be used as precursors for abrasives or ceramics. Their filmogenous properties due to the fine size of the particles and to the rheology of their suspension permit them to be used as thin coatings (thin layers).
