Antimony pentoxide (Sb2O5) is an inorganic ceramic oxide compound used primarily as a flame retardant additive and in specialized optical and electronic applications. It is valued in polymer composites and coatings for its ability to suppress flammability while maintaining material processability, and finds niche use in catalytic systems and advanced ceramics where chemical stability and high-temperature performance are required. Engineers select this material when flame retardancy must be achieved without halogenated additives, making it relevant for industries with strict environmental or toxicological constraints.
