Hydrofluoric Acid:
Hydrofluoric acid (HF) is a building block for almost all fluorine compounds. HF can be produced directly from the mineral Fluorite, but also as a by-product of phosphoric acid. 

Market Dynamics:
HF is primarily used in oil refining, as well as steel and aluminum production making oil&gas and construction key industries.Refineries use it as a catalyst to create high-octane fuel.
