· As4 Os2

As₄Os₂ is an intermetallic ceramic compound combining arsenic and osmium, belonging to the family of refractory metal compounds. This material exists primarily in research contexts rather than established industrial production, with potential applications in high-temperature structural applications, catalysis, or specialized electronic devices where the extreme hardness and thermal stability of osmium-based ceramics are leveraged.
