· JVASP-17314· CrAs2

CrAs₂ is an intermetallic compound composed of chromium and arsenic, belonging to the class of binary metal arsenides. This material is primarily of research and materials science interest rather than established commercial use, investigated for potential applications in thermoelectric devices, semiconducting materials, and high-temperature structural applications where intermetallic compounds offer novel property combinations. The chromium-arsenic system is studied for its potential to exhibit useful electronic, magnetic, and mechanical properties that could enable specialized engineering solutions in extreme environments or advanced device applications.
