  • Applications

    Tellurium hexafluoride (CAS 7783-80-4) is primarily used as a fluorinating agent and as a volatile precursor to prepare tellurium fluorides and other tellurium compounds; it also serves as a gas-phase source for chemical vapor deposition (CVD/MOCVD) to deposit Te-containing films for electronics and photovoltaic applications; it is used as a raw material to synthesize other tellurium fluorides and compounds in materials research and development; due to its toxicity and corrosivity, it is handled in specialized industrial facilities under strict safety controls and regulatory compliance.
