Applications of 7784-25-0
| Industry | Application | Process |
|---|---|---|
| Water Treatment | Used as a flocculant for purification of drinking water and wastewater | Neutralizes the charge of colloidal particles in water and bridges them to form large flocs, which settle and separate |
| Papermaking | Acts as a precipitating agent in rosin sizing to improve paper water resistance | Reacts with sodium rosin soap in pulp to form insoluble rosinic acid aluminum, which deposits on fiber surfaces |
| Textile Dyeing and Printing | Functions as a mordant to enhance dye fixation on fibers | Forms insoluble lakes with dye molecules, improving color fastness and brightness |
| Fire-Retardant Materials | Incorporated into flame-retardant treatment solutions for wood and textiles as a synergistic flame retardant | Decomposes upon heating to release crystalline water and form an alumina protective layer that suppresses flame spread |
| Catalyst Support | Serves as a substrate material for catalysts used in petroleum cracking and desulfurization | Converted by high-temperature calcination into porous γ-Al₂O₃, providing high specific surface area and acidic sites |
| Cosmetics | Used as an astringent in antiperspirant products (concentration limited to ≤0.6%) | Induces mild coagulation of epidermal proteins, temporarily constricting sweat ducts |
