A process as claimed in claim 1, wherein said fused mixture is supported on a carrier united water fluoridating water. While the same process can be used for small water supplies, the time, eliort, and technical skill required makes it impractical for the average householder. References Cited in the file of this patent UNITED STATES PATENTS 2,126,793 MacIntire Aug. has been established as desirable for the purposes of dental carie control without the risks attendant upon continued exposure to higher concentrations. Charcoal and many other materials can be used for cases where the active chemical is not fused on the carrier. EXAMPLE III A mixture of powder consisting of 12 percent precipitated calcium fluoride in tri-calcium phosphate was fused by heating to about 1400 C. In an illustrative form, the fluoridation tank is 12 inches in diameter and 48 inches in height. Brazil Brazil is the second most extensively fluoridated country in the world after the United States. The fluorides and phosphates of magnesium canalso be used in the process as can mixtures of calcium and magnesium and phosphates. The fused mass was ground and screened to 4080 mesh. An object of the instant invention, therefore, is the implementation of a process for fluoridating water wherein uniform control of the fluoride ion concentration within the safe established limits can be assured. 1, installed on the influent and efliuent sides of the fluoridation vessel respectively, provide means of controlling flow in the tank for cleaning and recharging purposes.

Calcium-fluoride-bearing materials commonly employed are precipitated calcium fluoride and fluorspar of high calcium fluoride content. The slurry was dried and the dried cake broken up and fused by an oxyacetylene flame. 0% by weight of the fluoride with calcium sulfate, and 0. Until recent years, the fluoride content of potable water supplies came under consideration only in terms of the action of fluoride to produce destructve mottling of teeth united water fluoridating water. In a further embodiment the mixture is supported upon a carrier, and may or may not be fused thereupon.

Moreover, the phosphate of calcium commonly employed is in the tri-basic or di-basic form. Powdered fluorspar, a ground native rock, can be substituted for the precipitated calcium fluoride in some cases.

The material was dried and fused at 1200 C. The active chemical was calculated to consist of 50 percent by weight calcium fluoride in di-calcium phosphate.
