Silicon tetrafluoride (SiF4, tetrafluorosilanee) is a binary inorganic substance obtained by the synthesis of silicon and fluorine.
- toxic gas
- colorless with a sharp odor
- heavier than air
- easily reacts with water
- dissolves in organic solvents
- thermally stable
- in solid form transforms into crystals
- in the process of producing hydrofluorosilicic acid;
- during cleaning and etching of silicon;
- as a source of silicon in the production of optical fiber;
- for hydrofluorination;
- in organic synthesis;
- as an analogue of refrigerants (freons) in cooling systems;
- for the production of synthetic cryolite and aluminum fluoride.
