Product specs
Buyer's Digest
Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Catalyst Carriers. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.
Original product description
This industrial-grade alumina micropowder carrier is supplied as white microsphere particles for use as a catalyst and catalyst carrier. The stated chemical formula is Al₂O₃, with alumina content of 98% minimum.
The identifies suitability as an alumina carrier for fluidized-bed catalysts and lists catalyst-related applications across chemical processing, petroleum additives, water-treatment chemicals, coatings, plastics, rubber, paper, leather, textiles, electronics chemicals, and surfactants.
Reported general specifications include Fe₂O₃ at 0.05% maximum, Na₂O at 0.10% maximum, pore volume of 0.35–0.45 ml/g, specific surface area of 160 m²/g, abrasion index of 3–5%, bulk density of 0.65–0.75 g/ml, R-Al₂O₃ phase, and particle size of 30–120.
Separate product variants are listed with D50 particle size of 65–75 μm, specific surface area of at least 150 or 200 m²/g, pore volume from 0.2 ml/g minimum to 0.5 ml/g minimum, bulk density from 0.65–1.08 g/ml, abrasion index of 0.6–2.0%, and Al₂O₃ content of at least 85%.
Because the published values differ between the general specification and individual variants, buyers should confirm the exact grade, test method, particle-size basis, pore-volume range, surface-area value, bulk density, abrasion index, phase, packaging format, sample availability, production lead time, minimum order quantity, payment terms, and suitability for the intended catalyst formulation before procurement.
