Property

CAS No.: 7783-61-1 Formula: F4Si Molecular Weight: 104.07900

Description

Silicon tetrafluoride or Tetrafluorosilane is the chemical compound with the formula SiF4. This tetrahedral molecule is notable for having a remarkably narrow liquid range (its boiling point is only 4°C above its melting point). It was first synthesized by John Davy in 1812.
