AsH3

AsH₃ (arsine) is a binary hydride compound that exists primarily as a gas at room temperature, classified here as a ceramic material due to its inorganic composition. In its solid or condensed states, it functions as a precursor chemical rather than a structural material, notable for its role in semiconductor manufacturing and thin-film deposition processes. The compound is valued in the electronics industry for metal-organic chemical vapor deposition (MOCVD) and hydride vapor phase epitaxy (HVPE) routes to produce high-purity gallium arsenide and other III-V semiconductors, where its toxicity and reactivity are managed within controlled process environments.
