· AsF3

Arsenic trifluoride (AsF₃) is an inorganic ceramic compound that exists as a volatile liquid at room temperature, belonging to the halide ceramic family. It is primarily encountered in specialized chemical processing, semiconductor manufacturing, and research contexts rather than structural applications, where it serves as a precursor for arsenic-containing materials and as a fluorinating agent in synthesis pathways. Engineers consider AsF₃ mainly in corrosive chemical environments and high-purity material synthesis where its reactivity and fluorine-donating capability provide advantages over conventional alternatives, though its toxicity and volatility require careful containment and handling infrastructure.
