Aluminum metaphosphate Cas 13776-88-0

Specialty Optical Glass: Key raw materials for phosphate, fluorophosphate, and laser glasses; enhances moisture resistance, lowers dispersion, and improves light transmission.
Ceramics and Refractories: High-temperature inorganic binders, glaze additives, and fillers for refractory castables; increases body strength and lowers firing temperatures; used for high-temperature linings in industrial kilns.
Eco-friendly Halogen-free Flame Retardants: Phosphorus-based flame-retardant fillers for plastics, rubber, and anti-corrosion coatings; forms a dense, heat-insulating aluminum phosphate protective layer at high temperatures; low-smoke and non-toxic; serves as a substitute for halogen-based flame-retardant systems.
Anti-corrosion and Water Treatment: Raw material for anti-rust metal coatings; chelates metals to form a protective passivation film; adsorbs and removes heavy metal ions from wastewater; also used as an additive in waterproof and anti-corrosive mortars.
