· Sc3Fe2Si3

Sc₃Fe₂Si₃ is an intermetallic compound combining scandium, iron, and silicon, belonging to the family of transition metal silicides. This material is primarily of research and development interest rather than established in high-volume production, investigated for applications requiring combinations of low density with structural rigidity and thermal stability. The scandium-iron-silicon system represents an emerging class of advanced alloys being explored for aerospace and high-temperature applications where lightweight, thermally stable materials with tailored elastic properties are advantageous over conventional alternatives.
