Description

Tetraaluminium Decahydroxide Sulphate is a specialized inorganic salt with a complex hydroxide-sulfate structure. This compound is valued for its dual functionality as a source of aluminum and sulfate ions, making it a versatile intermediate in industrial synthesis. It is primarily sought by manufacturers in the water treatment, paper, and specialty chemical sectors for applications requiring controlled aluminum release and flocculation properties.

Application

• Water Treatment Coagulant: Acts as a high-efficiency flocculant for the removal of suspended solids and phosphates in industrial and municipal wastewater treatment plants.
• Paper Manufacturing: Used in the production of paper and paperboard as a retention aid and sizing agent to improve sheet formation and water resistance.
• Catalyst Support & Precursor: Serves as a key precursor material for the synthesis of advanced alumina-based catalysts and adsorbents used in petrochemical refining.
• Fire Retardant Filler: Incorporated into polymers, rubbers, and coatings to enhance fire resistance and smoke suppression properties.
• Ceramic & Refractory Binder: Functions as a high-temperature binder and setting agent in the formulation of advanced ceramics and refractory materials.
• Antiperspirant Active Ingredient: Utilized as a raw material in the synthesis of aluminum chlorohydrate and other aluminum salts for personal care products.

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). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can lead to caking or changes in chemical properties.
