Aluminum Hydroxide Powders

We offer a wide range of aluminum powders which vary in density and particle size distribution.

Aluminum hydroxide dried gel products (powders) are typically used in wet granulation processes to manufacture antacid tablets. The aluminum assay for all products is not less than 76.5% on an Al(OH)3 basis or not less than 50% on an Al2O3 basis. The choice of which grade of aluminum powder to use is a formulation decision. The pharmaceutical formulator should select a grade based on desired tablet size, tablet hardness, or process parameters.
