It's colorless,transparent,liquid,as etchant for glass and metal cleaner,used to produce fluorine plastic and fluorine rubber .

1. It is a strong oxidant and sole raw material for making the element of fluorine.

2. It is important main raw material for inorganic fluoride and alll kinds of organic fluoride.

3. The use of fluorosilicates: metal surface treatment agent,  the oil recovery additive.
