One of several
companies, LCI,
sells fluoride to municipalities. Read about LCI's recommended
uses of fluoride. Here are some excerpts from their web page.
Founded in
1983, LCI LTD started as a supplier of fluorides to municipalities
for fluoridation of their potable water systems.
In 1993,
LCI purchased a Hydrofluoric Acid plant, Norfluor, S.A. de C.V.
in Juarez, México. Today, LCI offers a wide range of specialty
fluorides for water fluoridation and industrial applications.
Properties
It is a 20 to 35 percent aqueous solution. It is a colorless
to straw yellow , transparent, fuming, corrosive liquid. It has
a pungent odor and irritating action on the skin.
Manufacture
Fluorosilicic
acid (Hydrofluorosilicic acid) is manufactured by two different
processes, resulting in products with different characteristics.
The
largest production of the acid is as a byproduct of phosphate
fertilizer manufacture.
A smaller amount is produced from HF and silica resulting in
a purer product at slightly higher strength. [Editor: this is
an EXACT quote from their web page, as of September 15, 1999]
