What is the uses of fluorine?

• Fluorine is a highly reactive element that is used in processing nuclear fuel, in producing plastics and as a glass etching solution.   
• It can also be found in toothpaste and drinking water, which help prevent dental cavities and it is a component in air conditioning and refrigeration.  
• Because of its highly explosive nature, it is also used in rocket fuels. 
• Fluorine is used to refine uranium, which is used in nuclear reactors. 
• Fluorine is a component of chlorofluorocarbons. Chlorofluorocarbons were used as refrigerants in air conditioning units and freezers until they were banned because of their contribution to ozone depletion. 
• Fluorochemicals, including many high-temperature plastics such as Teflon, are also made using fluorine. 
• Hydrofluoric acid can dissolve glass and is used to etch the glass in light bulbs and in other products.
