'''四氟氧化钨'''是一种[[无机化合物]]，化学式为WOF<sub>4</sub>，易水解。其反应活性类似于[[六氟化钨]]。<ref name=Zhu>朱文祥. 无机化合物制备手册. 化学工业出版社, 2006. pp 269 【Ⅵ-132】 四氟氧钨. ISBN 7-5025-8537-0</ref>

==制备==
WOF<sub>4</sub>可由[[氟气]]于230~400℃和[[三氧化钨]]反应得到：<ref name=Zhu />
: WO<sub>3</sub> + 2 F<sub>2</sub> → WOF<sub>4</sub> + 2 O<sub>2</sub>

它也可以由钨和[[氧气]]和[[氟气]]的混合物在高温下反应而成，<ref name="Dale L. Perry" />[[六氟化钨]]的部分水解也能产生WOF<sub>4</sub>：<ref name="Laura Mendicino">{{cite book | last=Mendicino | first=L. | author2=Electrochemical Society.

:<chem>WF6 + H2O -> WOF4 + 2 HF</chem>
[[四氯氧化钨]]和[[氟化氢]]的反应也会产生WOF<sub>4</sub>：<ref name="Erik Lassner, Wolf-Dieter Schubert">{{cite book | last=Lassner | first=Erik | last2=Schubert | first2=Wolf-Dieter | title=Tungsten : Properties, Chemistry, Technology of the Element, Alloys, and Chemical Compounds | publication-place=Boston, MA | date=1999 | isbn=1-4615-4907-8 | oclc=1113605323 |page=168}}</ref>
:<chem>WOCl4 + 4HF -> WOF4 + 4HCl</chem>
WOF<sub>4</sub>还可以由[[氟化铅]]和[[三氧化钨]]在700 °C下反应而成：<ref name="Erik Lassner, Wolf-Dieter Schubert" />
:<chem>2PbF2 + WO3 -> WOF4 + 2PbO</chem>

== 性质==
四氟氧化钨是无色固体，会水解成[[钨酸]]：<ref name="Dale L. Perry" /><ref name="Laura Mendicino" />
:<chem>WOF4 + 2 H2O -> WO3 + 4 HF</chem>
