FeAs2 is an iron arsenide intermetallic compound that belongs to the family of transition metal pnictides. This material is primarily of research interest rather than established industrial production, studied for its potential electronic and structural properties in the context of iron-based superconductors and semiconductor applications. The compound's relatively high elastic stiffness and metallic character make it a candidate for investigation in high-performance electronic devices, though practical engineering applications remain limited and largely experimental.
