Antimony pentoxide is primarily used as a flame retardant synergist, enhancing the effectiveness of halogenated flame retardants in various materials. It also serves as a catalyst in the production of PET plastics and as a precursor in the synthesis of other antimony compounds.
Major production occurs in China, Russia, and Tajikistan, with China being the dominant producer. However, recent export restrictions from China have affected global supply chains.
While generally considered safe, it can cause skin and eye irritation. Appropriate personal protective equipment, such as gloves and eye protection, should be used when handling the compound.
Strong oxidizing agent (Sb in +5 oxidation state), being (Amphoteric) reacts with both acids and bases, and converts to antimony trioxide (Sb₂O₃) under reducing conditions.
