Description

Tetraaluminium Trichloride Nonahydroxide is a specialized inorganic aluminum compound with a unique mixed hydroxide/chloride composition. This material serves as a versatile precursor and active component in advanced material synthesis and industrial processes. It is particularly valuable for manufacturers in the catalyst, ceramic, and specialty chemical sectors seeking a controlled source of aluminum for high-performance applications.

Application

• Catalyst & Catalyst Support Precursor: Used in the synthesis of solid acid catalysts, including those for petrochemical refining (e.g., alkylation, isomerization) and organic synthesis.
• Advanced Ceramics & Refractories: Acts as a key starting material for producing high-purity aluminum oxide (alumina) ceramics, fibers, and refractory binders after thermal treatment.
• Flame Retardant & Smoke Suppressant Additive: Incorporated into polymer composites, coatings, and textiles to enhance fire resistance and reduce smoke emission.
• Inorganic Binder & Coating Agent: Utilized in the formulation of high-temperature resistant coatings, adhesives, and sealants for industrial applications.
• Water Treatment Coagulant Aid: Functions as an auxiliary coagulant to improve floc formation and turbidity removal in potable and wastewater treatment processes.
• Paper Sizing Agent: Employed in the paper manufacturing industry to improve water resistance and printability of paper products.
