"On the Source of Sodium Fluoride"
Sodium fluoride comes from its source, which can be quite studied.
The source of sodium fluoride first comes from the natural heritage of heaven and earth. Between mountains and rivers, in ore veins, or fluoride-containing ores, after years, weathered and eroded by water. Fluoride migrates with water flow, and in specific places, it meets with elements such as sodium, gradually forming the embryonic form of sodium fluoride.
In addition, the rise of industry is also the way of sodium fluoride formation. In the chemical process, fluorine-containing raw materials, such as fluorite, are chemically reacted with sodium-related substances. The principle of its reaction follows the rules of chemistry, so that fluorine and sodium are combined to obtain sodium fluoride. This industrial product, due to the controllability of craftsmanship, is more naturally generated, or more pure.
There is also the biological world, although the main source of non-fluorinated sodium, it is also involved. Some organisms absorb and convert fluorine and sodium elements when ingesting nutrients and metabolizing. Although the amount of sodium fluoride produced in their bodies is small, it is also a corner of the source of sodium fluoride.
In summary, the source of sodium fluoride, natural, industrial production and biological transformation, each has its own path, and the origin of co-constitutive sodium fluoride is also.
