ceramic

· K2NaAs

K2NaAs is an inorganic ceramic compound containing potassium, sodium, and arsenic, classified as a mixed-metal arsenide ceramic. This is a research-phase material studied primarily in solid-state chemistry and materials science contexts rather than a mature engineering material with established industrial production routes. The compound belongs to the broader family of multinary arsenide ceramics, which are investigated for potential applications in semiconducting, photonic, or thermal management systems where the unique combination of constituent elements offers targeted electronic or structural properties.
