· KUO3

KUO3 is a potassium uranium oxide compound belonging to the mixed-metal oxide semiconductor family. While not widely established in commercial production, materials in this class are of research interest for nuclear fuel chemistry, specialized catalysis, and studies of uranium-bearing ceramics under extreme conditions. Engineers would consider KUO3 primarily in nuclear science contexts or advanced materials research rather than conventional industrial applications.
