Germany, the United States, and Japan are the leading exporters of SELENIUM HEXAFLUORIDE (CAS 7783-79-1), collectively accounting for over 65% of global export value in 2023–2024; major importers include South Korea, Taiwan, and the Netherlands, driven by semiconductor and advanced materials manufacturing demand. Trade volumes have remained relatively stable since 2022, with modest growth in Asian imports coinciding with upward pressure on SELENIUM HEXAFLUORIDE prices amid tightening supply chains for high-purity specialty gases.
Selenium hexafluoride is a colorless, nonflammable, highly volatile gas at room temperature with a pungent, irritating odor. It is an inorganic fluorinated compound and belongs to the class of chalcogen halides. Primarily used as a fluorinating agent and etchant in semiconductor manufacturing, it serves in plasma etching processes for silicon-based materials and microelectromechanical systems (MEMS). It also functions as a precursor in the synthesis of selenium-containing fluoropolymers and specialty inorganic fluorides. Its applications are concentrated in electronics fabrication and advanced materials research.
Selenium hexafluoride is used as a gaseous electric insulator(146). It may be prepared by passing gaseous fluorine overfinely divided selenium in a copper vessel. Industrial seleniumexposure is common for makers of arc light electrodes,electric rectifiers, and semiconductors.
Selenium hexafluoride is a nonflammable, colorless gas. Repulsive odor.
