四氟化矽（化學式：SiF4）是最常見的矽氟化物。無色氣體，遇水發生水解生成氟矽酸，在潮濕空氣中發煙。沸點僅高於熔點4 °C。首先由John Davy (chemist)（英語：John Davy (chemist)）在1812年合成。 應用於微電子行業和有機合成中。 火山爆發時的煙霧中也含有大量的四氟化矽。 WebFive_Seconds_After_You_DieS c S c BOOKMOBIÝo È&p .Ô 7D >x F MÍ Uˆ ]_ dø lø t³ A „> ‹Ï “š šý £n"« $³ &» (ÂÏ*Êk,Ò .Ùï0áâ2é€4ðÈ6ø·8 ·: ¢ 5> ¨@ AB (ZD /ðF 7ÇH ?½J GÁL OpN VìP ^~R f T môV uÝX }—Z …~\ o^ • ` 1b ¥•d Üf ¶!h ¾!j Æ@l Îln Ölp Þ-r æ t íþv õøx ý z V ...
