What is the use of fluorine?

Fluorin is a light element classified as a halogen, which is the most electronegative element known and is therefore highly susceptible to linking with metal elements in nature to form salt. The use of fluorine includes extended applications in consumer products such as toothpaste, oral ox and as an additive to water supplies in some countries such as the US. In its elementary form, the use of fluorine also includes a conventional etching chemical for glass or silicon substrates in the production of semiconductors and as a etching compound of hydrophluoric acid (HF). This reactive natural fluorine has valuable glass in the production of microprocessors, computer and television displays and sensors of the microelectromechanical system (MEMS). Combined with ethylene, it also forms a coating without friction used in dishes known as polytheterafluorethylene (PTFE) .elding metals together and cutting patterns to glass or icing of its surface. Commercial production of chemicals increased rapidly at the beginning of the 20th century when chlorine compounds wereOfluorocarbon (CFC) originally made in the 1920s as refrigeres for commercial, residential and automotive air conditioning systems. PTFE surfaces were also invented and expanded at the end of the 30th year. Other use of fluorine is the separation of uranium, so heavy metal can serve as a fuel for nuclear power plants and as an element allowing oxidizers in missile fuel.

While CFC compounds were later discovered that they were exhausting the protective ozone layer of the Earth, they were replaced by other compounds that still contain fluorine element, such as hydrophluorocarbones (HFC). The European Union has banned the use of further wording of the well -known fluorochlorohydrocarbones as a coolant in 1995, as they were also intended as chemicals with ozone. While HFC do not decompose into compounds in the upper atmosphere that destroys the ozone layer, it is known to contribute to the process of global warming, so that also postThey gradually discard.

While the use of fluorine is diverse, the element is not without its risks, as it can be highly toxic, corrosive and explosive. As a hydrophluoric acid used in the semiconductor and bulb production industry, it is a colorless, without odorless liquid compound that resembles water and seems harmless if it spills into the skin surface. However, HF has a strong tendency to bind to calcium and any of the acids spilled on the skin is quickly soaked in skin and into bones where they gradually dissolve and binds with calcium in other tissues, leading to intense pain and possible death. The use of fluorine in water supply also has bontroversis due to the fact that in sufficiently high concentrations or after a long exposure period it can be harmful to human health. Almost 20 industrialized nations since 2000, including India, Germany and Japan, have a policy of not adding any fluorin content into public water supply despite evidence that low concentrations prevent tooth decay and othersDental problems, especially in children.
