Used in thermoelectric devices due to its ability to convert waste heat into electricity, especially at high temperatures. It is a promising material for eco-friendly power generation because it is non-toxic and composed of abundant elements. Commonly applied in thermocouples and high-temperature sensors. Also investigated for use in semiconductor devices and as a coating material in industrial applications where oxidation resistance is required. Its optical properties make it suitable for infrared detectors and optoelectronic components.
