· JVASP-52621· K5As4

K5As4 is an inorganic ceramic compound in the potassium-arsenic oxide system, likely a mixed-valence ceramic with potential applications in specialized industrial contexts. While not widely documented in mainstream engineering databases, this material represents a research-phase compound with properties suited to applications requiring moderate stiffness and thermal stability in chemically demanding environments. Engineers would consider K5As4 primarily in niche applications where arsenic-containing ceramics offer unique chemical resistance or functional properties not achievable with conventional oxides.
