Rb2Ni3Se4
metal· JVASP-11468· Rb2Ni3Se4
Rb2Ni3Se4 is an intermetallic compound composed of rubidium, nickel, and selenium, belonging to the family of ternary metal chalcogenides. This is an experimental research material rather than an established engineering alloy, studied primarily for its electronic and structural properties within materials physics and chemistry contexts. Compounds in this family are investigated for potential applications in thermoelectric devices, solid-state electronics, and catalysis, where the combination of transition metals (Ni) with chalcogens (Se) and alkali metals (Rb) can produce tunable band structures and ion-transport characteristics.
