· KSbO3

KSbO3 is a potassium antimony oxide ceramic compound belonging to the perovskite family of semiconductors, characterized by its mixed-valence metal oxide structure. While primarily studied in research contexts, this material shows potential in optoelectronic and photocatalytic applications due to its semiconductor bandgap and crystal structure; it represents an emerging alternative in oxide-based semiconductors for environments where bismuth-free or lead-free formulations are required. Engineers would consider this material for next-generation functional ceramics where chemical stability and non-toxic heavy metal alternatives are design constraints.
