Used as an inert electrode material in high-temperature and highly corrosive environments due to its exceptional resistance to oxidation and chemical attack. Commonly employed in electrochemical applications such as molten salt electrolysis and high-temperature sensors. Frequently used in research and industrial settings for spark erosion processes and as a filament in specialized lighting and electron beam equipment. Its high melting point and stability make it ideal for use in extreme conditions where other metals would fail. Also utilized in the production of single-crystal growth systems and as a component in precision instruments requiring dimensional stability under thermal stress.
