Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Adsorbents And Desiccants. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
This industrial-grade activated alumina is supplied as white, spherical porous granules for dehydration and adsorption duties. The listed composition is at least 93% Al2O3, with SiO2 limited to 0.08%, Fe2O3 to 0.04%, and Na2O to 0.45%.
The material is described as odorless, non-toxic, and insoluble in water and ethanol. Published technical values include a surface area of at least 300 m²/g, pore volume of at least 0.40 ml/g, bulk density of 0.68–0.75 g/ml, static adsorption capacity of at least 18%, and water absorption of at least 50%.
Standard particle-size options in the technical table are 1–3, 3–5, 4–6, and 5–8 mm. The description also lists 2–4 mm and 0.5–1.0 mm options. Crushing strength depends on particle size, ranging from at least 60 N per particle for 1–3 mm spheres to at least 200 N per particle for 5–8 mm spheres.
Buyer confirmation before ordering: specify the required particle-size distribution, order quantity, packaging format, and target dehydration or adsorption process.
Ask for a batch-specific specification or certificate of analysis and confirm the test methods used for surface area, pore volume, adsorption capacity, water absorption, and crushing strength.
If the material will , confirm the required treatment conditions, capacity target, operating pH, media life, regeneration procedure, and applicable regulatory requirements.
Also confirm whether the requested grade is covered by the listed RoHS, EC, REACH, and TSCA certifications and obtain the relevant current documentation.
