· NiAs2

NiAs₂ is a nickel arsenide intermetallic compound that belongs to the metal-metalloid family of materials. It is primarily of interest in materials research and metallurgical studies rather than high-volume industrial applications, with potential relevance in semiconductor research, electronic device development, and specialized alloy systems. The compound is notable for its rigid crystalline structure and potential use in high-temperature or corrosion-resistant applications where nickel's properties can be leveraged through arsenide bonding.
