Antimony trioxide (Sb₂O₃) is a ceramic semiconductor compound that exists in multiple crystal phases, primarily used as a flame retardant additive and in specialized optical and electronic applications. It is widely employed in plastics, textiles, and coatings to enhance fire resistance, often in combination with halogenated compounds for synergistic effect. The material is also investigated for infrared optics, gas sensors, and photocatalytic devices, making it valuable in contexts where thermal stability and chemical inertness are required alongside flame-suppression functionality.
