Description

Gibbsite (Al(OH)3) is a primary mineral form of aluminum hydroxide and a key industrial precursor for alumina and aluminum production. Its consistent purity and reactivity make it a critical raw material for manufacturing processes requiring a reliable source of aluminum. This compound is essential for industries involved in ceramics, flame retardants, and water treatment. The product is supplied as Gibbsite (Al(OH)3) CAS NO 14762-49-3.

Application

• Primary feedstock for the production of alumina (Al2O3) via the Bayer process.
• Flame retardant and smoke suppressant filler in polymers, cables, and construction materials.
• Precursor for the manufacture of aluminum chemicals, including aluminum sulfate and polyaluminum chloride (PAC) for water purification.
• Raw material in the production of ceramics, glass, and abrasives.
• Filler and extender in paints, coatings, and adhesives to modify rheology and brightness.
• Starting material for the synthesis of zeolites and other catalytic supports.
• Component in pharmaceutical and cosmetic formulations as an antacid or mild abrasive.
• Use in paper manufacturing as a coating pigment and filler.

Quality Control

Our Gibbsite is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity. Quality parameters are verified against relevant industrial and chemical standards. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption and caking. Keep away from incompatible materials such as strong acids.
