Xenon difluoride (XeF₂) is a compound with the CAS number 13709-61-0. It is a powerful fluorinating agent used in various applications, notably in semiconductor manufacturing and inorganic chemistry. Here are some characteristics of xenon difluoride:
Characteristics of Xenon Difluoride:
Physical Properties:
XeF₂ is a colorless solid at room temperature.
It has a melting point of around 245 K (−28.15 °C or −18.67 °F).
It sublimes readily at room temperature under vacuum or at slightly elevated temperatures.
Chemical Properties:
XeF₂ is a powerful fluorinating agent, capable of converting many compounds to their fluorinated derivatives.
It is used in semiconductor processing for etching silicon, silicon dioxide, and other materials.
It is less reactive than other xenon fluorides such as XeF₄ and XeF₆, but still very reactive towards many elements and compounds.
Handling and Safety:
XeF₂ is extremely toxic and corrosive.
It can cause severe burns and eye damage upon contact.
Inhalation can lead to respiratory tract irritation and possible lung damage.
It should be handled in a well-ventilated area using appropriate personal protective equipment.
Storage:
XeF₂ must be stored in a cool, dry place away from incompatible substances.
It should be kept under an inert atmosphere to prevent decomposition and reaction with moisture or other reactive gases.
