Cobalt selenide (CoSe) is an inorganic compound characterized by its formation of cobalt and selenium in a 1:1 molar ratio. It typically appears as a black or dark gray solid and is known for its semiconductor properties, making it of interest in various electronic applications. CoSe exhibits a layered crystal structure, which can influence its electrical and optical properties. The compound is relatively stable under ambient conditions but can react with strong acids, releasing selenium and forming cobalt salts. Cobalt selenide is also noted for its potential toxicity, particularly due to the presence of selenium, which can be harmful in certain forms and concentrations. As a result, handling CoSe requires appropriate safety precautions to mitigate exposure risks. In terms of applications, CoSe has been explored in the fields of photovoltaics, thermoelectrics, and as a catalyst in chemical reactions. Its unique properties continue to be the subject of research, particularly in the context of advanced materials and nanotechnology.
