FAQ

Frequently Asked Questions

Yes, it is toxic, corrosive, and reacts violently with water to produce dangerous acids.

They are the same; 'silicon tetrafluoride' is the specific, systematic name, while 'silicon fluoride' is a less precise general term that could refer to other fluorides of silicon.

No, it reacts with glass (which contains silica). It is typically stored in specialised, passivated metal cylinders.

It is often produced by treating silicon dioxide (sand) or silicates with hydrofluoric acid, or as a byproduct in the phosphate fertilizer industry.
