Product Description
Aluminium hydroxide is a key inorganic compound. It presents as a white amorphous powder, insoluble in water and ethanol. As a typical amphoteric hydroxide, it can react with both acids and alkalis. Industrially, it's produced mainly via the Bayer Process and Sintering Process. It has multiple functions like flame - retardant, smoke - suppressing and filling, so it's an important raw material for preparing aluminium salts. Clinically, it's used as a weak - alkaline compound to neutralize gastric acid, protect the gastric mucosa, and treat conditions such as excess gastric acid, gastric and duodenal ulcers. It also finds applications in industries like plastics, rubber, coatings, and building materials. Moreover, it serves as a fundamental raw material in the electrolytic aluminium industry.
This material serves multiple essential roles: as a flame-retardant, smoke suppressant, and filler, it is integral to manufacturing aluminium salts. In clinical settings, its mild alkaline properties make it a valuable ingredient in medications, effectively neutralizing stomach acid, safeguarding the gastric lining, and addressing issues like acid reflux and peptic ulcers. Beyond healthcare, it is widely utilized in industries such as plastics, rubber, coatings, and construction materials. Additionally, it forms a foundational component in the electrolytic aluminium production chain, underpinning the metal's extraction and refining processes.

Application
Raw Material for Aluminum Salt Production: As a basic raw material, it is used to produce aluminum salts such as aluminum chloride and aluminum sulfate. These aluminum salts can be further applied in water treatment (e.g., as flocculants for water purification), papermaking (to improve paper sizing performance), and the preparation of petrochemical catalysts.
Flame Retardant and Filler Material: When heated, it decomposes to release water and absorb heat, effectively inhibiting material combustion. It is often added as a flame retardant to polymer materials like plastics, rubber, and cable sheaths, while also serving as a filler to improve the mechanical properties and processing performance of materials.
Ceramics and Refractory Materials: As an additive in ceramic manufacturing, it enhances the high-temperature resistance and mechanical strength of ceramics. It is also used to produce refractory materials such as firebricks and refractory fibers, applied in high-temperature industrial kilns, metallurgical equipment, and other scenarios.
Coating Additive: When added to coatings, it can enhance the weather resistance, corrosion resistance, and fire - proof performance of the coating, and meanwhile improve the rheological properties of the coating to make the construction more uniform.
Building Material Filler: It is used in the production of building boards, pipes, and sealing materials to improve the hardness, wear resistance, and dimensional stability of materials. It is commonly used in artificial marble, wall insulation materials, and other applications.
Metallurgy and Electrolytic Aluminum Industry
Intermediate Product in Aluminum Smelting: Aluminum hydroxide is extracted from bauxite through processes such as the Bayer process, and then decomposed into alumina by high - temperature calcination. Finally, it is used in the electrolytic production of metallic aluminum. It is a key intermediate raw material in the aluminum industrial chain from ore to metal.
Packaging & Shipping
It should be packed in sealed packaging bags, woven bags or barrels. The common packaging materials are polyethylene plastic bags with composite woven bags outside to ensure no damage to the packaging and prevent dust leakage or moisture absorption. For bulk industrial goods, ton bags or containers can be used for sealed storage.
