Description

Pyroantimonate is an inorganic salt of antimony, widely utilized as a specialized reagent and intermediate in advanced material synthesis. Its primary commercial value lies in its role as a precursor for flame retardants and as a key component in the formulation of specialty glasses and ceramics. This product is essential for manufacturers and R&D laboratories in the electronics, polymer, and inorganic materials sectors seeking to enhance material properties such as thermal stability and flame resistance.

Application

• As a key precursor in the synthesis of halogen-free flame retardants for engineering plastics and polymers.
• In the production of specialty glasses and ceramics, where it acts as a fining agent and modifies optical properties.
• As a catalyst or catalyst component in select organic synthesis and petrochemical processes.
• In analytical chemistry as a reagent for the detection and determination of specific ions.
• For research and development in advanced material science, particularly in developing thermally stable composites.
• In the formulation of certain types of pigments and opacifiers.
