NaAlSe

NaAlSe is an intermetallic compound combining sodium, aluminum, and selenium—a rare ternary phase that falls outside conventional metallurgical families. This material is primarily of research interest rather than established industrial use; it belongs to the family of sodium-containing intermetallics and selenide compounds being investigated for potential applications in thermoelectric devices, photovoltaic materials, and solid-state electronics where the combination of light and heavy elements can produce unusual electronic and thermal transport properties.
