Description

γ-Aluminum Oxide (γ-Alumina) is a high-surface-area, metastable polymorph of aluminum oxide, distinguished by its unique porous structure and catalytic properties. This material is critical for applications requiring high thermal stability and chemical inertness, serving as an essential catalyst support and adsorbent. It is widely utilized in the petrochemical, environmental, and pharmaceutical industries for processes such as hydrocarbon reforming, exhaust gas purification, and chromatography.

Application

• Catalyst Support: Primary carrier for precious metal catalysts (e.g., platinum, palladium) in automotive catalytic converters and petroleum refining processes like hydrodesulfurization.
• Adsorption & Separation: Used as a desiccant, in gas drying, and as a stationary phase in chromatography for the purification of chemicals and pharmaceuticals.
• Petrochemical Processing: Acts as a catalyst or support in reactions such as dehydration, Claus process for sulfur recovery, and olefin production.
• Ceramics & Composites: A precursor material for advanced ceramics, coatings, and composite materials requiring high hardness and thermal resistance.
• Environmental Remediation: Employed as an adsorbent for the removal of heavy metals, fluorides, and other contaminants from wastewater.
• Electronic Materials: Serves as a substrate or insulating layer in microelectronics and as a component in sensors.

Quality Control

Our γ-Aluminum Oxide is manufactured under a stringent quality management system. Each batch undergoes comprehensive analysis to ensure it meets precise specifications for surface area, pore volume, particle size distribution, and chemical purity. Certificates of Analysis (COA) detailing all test results are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, store in a cool, dry place at room temperature (15-25°C) with low humidity to prevent moisture absorption and caking. Keep away from strong acids and fluorides.
