Description

Boehmite CAS NO 1318-23-6 is a versatile aluminum oxide hydroxide (γ-AlOOH) widely recognized for its unique combination of thermal stability, high surface area, and excellent dispersibility. This material is a critical precursor and functional additive in advanced ceramics and high-performance coatings, where its properties directly influence product durability and performance. It is essential for manufacturers in the catalyst, lithium-ion battery separator, and flame-retardant polymer composite industries seeking to enhance material characteristics and process efficiency.

Application

• Catalyst & Catalyst Support: Used as a high-surface-area carrier for active catalytic components in petrochemical and refining processes.
• Lithium-Ion Battery Separator Coatings: Serves as a key ceramic coating material to improve thermal stability, puncture resistance, and electrolyte wettability of polyolefin separators.
• Flame Retardant & Smoke Suppressant: Incorporated into polymers, wires, and cables to enhance fire safety performance by promoting char formation.
• Advanced Ceramics & Composites: Acts as a sintering aid and precursor for producing high-purity alumina ceramics, transparent ceramics, and fiber-reinforced composites.
• Anticorrosion & Protective Coatings: Functions as a nano-filler in epoxy, polyurethane, and other resin systems to improve barrier properties and mechanical strength.
• Polishing & Abrasives: Employed in the formulation of precision polishing slurries for semiconductor wafers, optical glass, and hard disk substrates.
• Adsorbents & Membranes: Utilized in the fabrication of porous adsorbent materials and inorganic membranes for filtration and separation applications.
• Pharmaceutical & Cosmetic Additive: Used as an inert carrier or rheology modifier in certain formulations.

Quality Control

Our Boehmite is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent chemical composition, phase purity, and controlled particle size distribution. Certificates of Analysis (COA) detailing key parameters such as Al2O3 content, crystalline phase (by XRD), and specific surface area (BET) are provided with every shipment. We support customer audits and can tailor specifications to meet specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to minimize exposure to atmospheric moisture, which can affect flowability and dispersion properties.
