Barium fluoride is a common ingredient in many toothpastes and mouthwashes. The benefits of using it are numerous however some people doubt its safety. There is also some controversy over its ability to prevent cavities in children. Is barium fluoride a healthy substance to use? In this article we will examine the safety issues concerning this popular but controversial whitening agent.
First of all, what is barium fluoride? Barium fluoride (BAF 2) is an ionic compound with the chemical formula BaF(FooFoo) 2. It is basically a silicate mineral that occurs naturally as the rare white mineral called frank dick. Under normal circumstances it takes the sodium fluoride (NaF) structure and in high-energy radiation it adopts the phosphorous structure.
Like calcium baf, it is highly insoluble in bromine and more resistant to vaporization in high-energy radiation. The insolubility ensures that in case of inhalation of the compound there will be less resistance to ozone. The less resistant it is to ozone, the less dangerous it will be to your health.
In 1977 a research study was conducted in the United States by the U.S. Environmental Protection Agency (EPA) examining the health hazards of exposure to barium fluoride. It was concluded that a high concentration of baf 2 was harmful and could even cause anemia. The concentration of barium fluoride found in the soil was below the level that was considered hazardous. The report stated that the level of exposure would be low enough not to result in immediate or long-term health hazards.
Based on this report, there are three common parameters used to measure the health risk of this mineral. They are the Refractive Index, the Spectral Properties, and the Biological-activity parameters. The Refractive Index measures the change in the transverse path of light, which can be determined from an experiment performed with irradiation. It is measured as a positive or negative number indicating how much loss of energy comes from scattering by the ultra-violet light when a light source is shone on it.
When comparing barium fluoride to its competitors, it has been found that the high-refractive index and the low-spectral-property combine to make this a superior material to fight off cancer causing UV rays. It also has high hardness and good elasticity, which make it suitable for the manufacture of playground equipment and safety nets. Since it has low vapor andoxides, it has a low evaporation rate, and its color blends well with its surroundings.
