· Sc1 Si1

Sc₁Si₁ is an intermetallic compound composed of scandium and silicon in a 1:1 stoichiometric ratio. This material belongs to the family of transition metal silicides, which are typically hard, refractory compounds studied for high-temperature and wear-resistant applications. As a scandium-silicon phase, Sc₁Si₁ remains largely in the research and development domain, with potential applications in advanced structural materials, coatings, and electronics where its thermal stability and hardness could provide benefits over conventional alternatives.
