· KBiO3

Potassium bismuth oxide (KBiO₃) is an inorganic ceramic compound with semiconductor properties, belonging to the class of mixed-metal oxides. This material is primarily of research interest for photocatalytic and optoelectronic applications, where its layered crystal structure and band gap characteristics make it a candidate for visible-light-driven processes and electronic devices. While not yet established in high-volume industrial production, KBiO₃ represents an emerging material in the bismuth-based oxide family, investigated for sustainability advantages (bismuth is less toxic than lead in comparable applications) and its potential in environmental remediation and energy conversion systems.
