Si4 Ru4

Si₄Ru₄ is an intermetallic compound combining silicon and ruthenium, representing a transition metal silicide in the semiconductor class with potential for high-temperature and electronic applications. This material is primarily of research interest rather than established industrial production, with its stiff mechanical properties and thermal stability making it a candidate for investigating advanced electronic devices, refractory coatings, or specialized high-temperature structural components where ruthenium's oxidation resistance and silicon's semiconductor behavior could be leveraged together.
