Used primarily in high-temperature environments due to its excellent oxidation resistance and thermal stability. Commonly employed as a heating element in industrial furnaces operating up to 1800°C, especially in oxidizing atmospheres. Applied in the semiconductor industry as a conductive material in integrated circuits and thin-film coatings. Also utilized in aerospace and turbine engines as a protective coating for components exposed to extreme heat. Its brittleness at room temperature limits structural use, but it remains valuable in specialized high-heat applications.
