ceramic

· Sb2S2O

Sb₂S₂O is an antimony sulfur oxide ceramic compound that combines antimony, sulfur, and oxygen in a mixed-valence structure. This material belongs to the family of chalcogenide ceramics and is primarily encountered in research and materials development contexts rather than mature commercial applications. The compound is of interest for its potential in optoelectronic devices, solid-state chemistry studies, and possibly photocatalytic applications where antimony-based oxysulfides have shown promise in light-responsive systems.
