The remarkable properties of activated alumina, a cornerstone in many industrial applications, stem from a sophisticated manufacturing process that transforms a common precursor into a highly efficient adsorbent. NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of producing this advanced material, ensuring its quality and performance for diverse needs.

The journey to activated alumina begins with aluminum hydroxide (Al(OH)3). This raw material is subjected to a carefully controlled calcination process. Calcination involves heating aluminum hydroxide to high temperatures, typically between 400°C and 600°C (750°F - 1100°F). During this thermal treatment, water molecules are driven off from the aluminum hydroxide structure through dehydration and dehydroxylation. This critical step results in the formation of aluminum oxide (Al2O3) in specific metastable crystalline phases, most commonly gamma-alumina (γ-Al2O3).

The magic of activation lies in the formation of an extensive network of microscopic pores and channels within the aluminum oxide structure. This intricate internal architecture dramatically increases the material's surface area, often exceeding 200 square meters per gram. It is this immense surface area, coupled with the polar nature of the alumina surface, that gives activated alumina its powerful adsorption capabilities. The material acts like a molecular sponge, attracting and trapping moisture and other polar contaminants from gases and liquids.

The resulting gamma activated alumina exhibits a unique combination of properties: high adsorption capacity, good mechanical strength (crush strength), chemical inertness, and thermal stability. These characteristics make it an invaluable desiccant for drying gases like compressed air and natural gas, an effective filter for removing fluoride, arsenic, and selenium from water, and a versatile carrier for catalysts in chemical reactions. NINGBO INNO PHARMCHEM CO.,LTD. meticulously controls these manufacturing parameters to produce activated alumina that meets stringent industrial specifications.
