· JVASP-56110· K3Bi

K3Bi is an intermetallic ceramic compound composed of potassium and bismuth, belonging to the class of ternary or complex ceramics. This material is primarily of research and developmental interest rather than established in high-volume industrial production, with investigation focused on its potential in solid-state applications including thermoelectric devices and energy conversion systems where bismuth-based compounds have shown promise.
