YbKSe2

YbKSe₂ is a ternary ceramic compound combining ytterbium, potassium, and selenium, belonging to the family of rare-earth chalcogenide materials. This is primarily a research material studied for its electronic and optical properties rather than an established industrial ceramic. The ytterbium chalcogenide family shows promise in thermoelectric applications, optical devices, and semiconductor research where rare-earth dopants or narrow-bandgap semiconductors are needed, though YbKSe₂ itself remains in the experimental phase and has not achieved widespread commercial adoption.
