High-Purity Porous Gamma Activated Alumina Balls | RFQ Sourcing Details

Product overview These white activated alumina balls are porous, predominantly gamma-phase alumina particles intended for industrial adsorption, drying, catalyst, and catalyst-carrier systems. The stated Al2O3 content is 92–95%, with sodium oxide, silica, and other constituents identified as possible impurities.

Available particle-size ranges are 1–2 mm, 2–3 mm, 4–6 mm, and 5–7 mm. Reported technical properties The material has a stated BET surface area of 200–400 m²/g, pore volume of 0.3–0.6 cm³/g, average pore size of 3–8 nm, and bulk density of 0.6–0.9 g/cm³.

Water adsorption is listed at 15–20% under 25°C and 60% relative humidity. For 3–5 mm spheres, the reported crush strength is at least 50 N per bead, while the stated attrition rate for spherical particles is no more than 0.5%. The listed regeneration range is 200–350°C under inert gas or vacuum.

Temperature resistance is described as up to 600°C for short exposure and no more than 400°C for long-term exposure. The material is stated to remain stable from pH 4 to 10 but to dissolve in strong acids or alkalis.

Potential industrial uses Supported application areas include compressed-air, natural-gas, and hydrogen drying;dehydration of refrigerants, organic solvents, lubricating oil, and transformer oil;water-treatment adsorption;waste-gas treatment;and use as a catalyst carrier in petrochemical and exhaust-treatment processes.

The source information also identifies laboratory drying towers and moisture-controlled cabinets as possible uses. Suitability for any specific contaminant, process stream, or regulated application requires validation against the buyer’s operating conditions.

Procurement questions to confirm Before ordering, buyers should request a lot-specific specification or test report and confirm the required bead size, Al2O3 content, surface area, pore structure, bulk density, crush strength, attrition rate, and adsorption capacity.

The target inlet moisture, required outlet dew point, flow rate, pressure, temperature, regeneration method, and expected cycle life should be reviewed with the supplier.

Buyers should also confirm chemical compatibility with the complete process stream, especially where strong acids, strong alkalis, or reactive contaminants are present.

For catalyst-carrier projects, confirm pore distribution, surface chemistry, loading method, thermal history, and compatibility with the intended active phase.

For water, medical-gas, or other controlled applications, independently confirm the required purity, contaminant limits, testing methods, and regulatory documentation.

Packaging options are listed as plastic bags, steel drums, and jumbo bags;the selected pack format, net weight, moisture protection, and lot traceability should be agreed before purchase.
