Fluorine Atom

Naturally occurring fluorine is composed of the pure 199F isotope. Its relative abundance in the earth crust as a whole is 0.027% by weight. Because of the extremely low solubility (solubility product 1.7 x 10-10 at 25 °C) of its most dominant minerals, the concentration of fluoride in seawater is very low (1.4 mg/L).

The most abundant natural sources of fluorine are the minerals fluorspar (CaF2) and cryolith (Na3AlF6). Fluoroapatite (Ca5(PO4)3F) is major component of tooth enamel, giving it its extreme mechanical strength and durability.

Unique Properties of Fluorine

Fluorine is the most electronegative element (electronegativity 3.98), and therefore occurs in its compounds exclusively in the oxidation state -1. The high electron affinity (3.448 eV), extreme ionization energy (17.418 eV) and other unique properties of fluorine are due to its ability to achieve nobel gas electron configuration by acquiring one electron. The fluorine anion is also the smallest (ion radius 133 pm) and least polarizable anion.

Synthesis of Perfluorocarbons

Tetrafluoroethylene (TFE) is the building block of all the chemicals in our catalog. TFE is made in the following process:

TFE can be self-polymerized to make polytetrafluoroethylene (PTFE):
