Product Description
Aluminium hydroxide stands as a pivotal inorganic compound, distinguished by its white amorphous powder form that remains insoluble in both water and ethanol. Renowned for its amphoteric nature, this compound demonstrates the unique ability to interact with both acidic and alkaline substances, showcasing remarkable versatility. Industrially, its production primarily relies on two key methodologies: the Bayer Process, tailored for bauxite with high aluminium oxide content, and the Sintering Process, suited for ores with lower aluminium-to-silica ratios. Functionally, it serves multiple critical roles: acting as a flame retardant, smoke suppressant, and filler, it is indispensable in the manufacturing of aluminium salts. In clinical applications, its mild alkaline properties make it a valuable agent for neutralizing stomach acid, protecting the gastric lining, and addressing conditions such as acid reflux, gastric ulcers, and duodenal ulcers. Beyond healthcare, it is widely employed across industries including plastics, rubber, coatings, and construction materials. Additionally, it forms the foundational raw material in the electrolytic aluminium production chain, underpinning the extraction and refinement of metallic aluminium.
This compound performs diverse critical functions: as a flame-retardant, smoke-suppressing agent, and filler, it is fundamental to the production of aluminium salts. In medical contexts, its gentle alkaline characteristics render it a vital component in pharmaceuticals, efficiently neutralizing gastric acid, protecting the stomach lining, and alleviating conditions like acid reflux and peptic ulcers. Outside of healthcare, it is extensively applied across sectors such as plastics, rubber, coatings, and construction materials. Furthermore, it constitutes a cornerstone of the electrolytic aluminium manufacturing process, serving as the basis for metal extraction and refining operations.

Application
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.
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.
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.
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.
Packaging & Shipping
Packaging should be sealed in bags, woven sacks, or barrels. Typically, it is encased in polyethylene plastic liners within composite woven bags to maintain package integrity, preventing dust leakage and moisture absorption. For large-scale industrial shipments, bulk storage in ton bags or sealed containers is recommended.
