Uses of Calcium Fluoride CaF2 Powder

The experiment generally uses calcium carbonate and hydrofluoric acid or repeated treatment of fluorite powder with concentrated hydrochloric acid or hydrofluoric acid to prepare calcium fluoride. The calcium fluoride minerals in nature are fluorite or fluorspar often in the form of gray yellow green purple etc. sometimes colorless transparent glassy brittle and markedly fluorescent.

The Corrosion of Titanium in Acids—The Rate of …

The potential of titanium is +0.26 volt in 1 N, and −0.353 and −0.342 volt in 6 N sulfuric or hydrochloric acid respectively, while in hydrofluoric acid it is −0.77 volt. Hence, titanium does not displace noble metals from their salt solutions until hydrofluoric acid or soluble fluorides are added to the above mentioned acids.
