High purity Antimony oxide (Sb2O3) Powders for applications in flame retardant, catalysts, batteries, and optoelectronics
Antimony oxide (Sb2O3) is an inorganic semiconducting material with high photon conductivity and superior chemical stability. It naturally occurs as the minerals valentinite and senarmontite.
Antimony based materials show great potential as anode materials for lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs), owing to their high energy density as well as long lifespan. Sb2O3 composite exhibits high specific charge capacity of 640.8 mA h g−1 at a current density of 0.2 A g−1 after 50 cycles in lithium-ion batteries. Sb2O3 anode exhibits a high capacity of 550 mA h g–1 at 0.05 A g–1 and 265 mA h g–1 at 5 A g–1 and a reversible capacity of 414 mA h g–1 at 0.5 A g–1 is achieved after 200 stable cycles in sodium-ion batteries.

Sb2O3 can greatly increase flame retardant effectiveness while used in combination with halogenated flame retardants as a synergist in coatings, plastics, fibre, paints, adhesives, rubber, and textiles. Antimony oxide also finds applications as catalyst in the production of polyethylene terephthalate (PET) and rubber, and as opacifying agent for glasses, ceramics, and enamels.
