What is Fluorine?

About Fluorine: 

• Fluorine comes from a calcium salt called calcium fluoride, or fluorspar.
• Fluorspar is mined and then treated with sulphuric acid at a high temperature to release hydrogen fluoride (HF).
• Hydrogen fluoride is then made to react with other compounds to create fluorochemicals.
• Fluorine is a highly reactive element used to make fluorochemicals,
• It is used to produce plastics, agrochemicals, lithium-ion batteries, and drugs.
• Issues with hydrogen fluoride
  • A major downside of this process is that HF is an extremely poisonous and corrosive liquid that irritates the eyes and respiratory tract even at low concentrations.
  • t also requires special transportation and storage requirements.
  • Hydrogen fluoride spills have occurred numerous times in the last decades, sometimes with fatal accidents and detrimental environmental effects.
• New procedure to obtain fluorine atoms
  • To avoid HF and to make the extraction process requires less energy, the researchers took inspiration from how the human body makes bones and teeth: through calcium phosphate biomineralisation.
  • They ground fluorspar in a ball-mill with potassium phosphate.
  • While fluorine is very reactive, calcium atoms prefer phosphorus even more, so the milling created calcium phosphate and another compound with fluorine atoms. They called the latter Fluoromix.
  • When Fluoromix was reacted with organic compounds, it could create around 50 fluorochemicals with up to 98% yield.

Q1) What is the role of calcium in the human body?

Calcium is an essential mineral for the human body, playing a crucial role in various biological processes, including bone formation, muscle contraction, nerve function, and blood clotting.
