  • Applications

    Aluminum triphosphate (CAS 13939-25-8) finds use mainly as a ceramic and refractory binder, where it helps form high-temperature cements and durable ceramic matrices. It is evaluated as a flame-retardant additive in polymer resins and coatings, contributing to char formation and thermal stability. The material can serve as a solid-acid catalyst or catalyst support in specialty chemical processes, enabling selective esterifications and condensations under moderate conditions. In coatings, inks, and adhesives, it can act as an inorganic binder or functional filler to improve adhesion and heat resistance. These applications span ceramics, polymers/coatings, and specialty chemical processing, with actual use governed by formulation needs and regulatory constraints.
