Chemical formula of Fluorspar is 

Fluorspar is CaF₂

Fluorspar, also known as fluorite, has the chemical formula CaF₂. It is a naturally occurring mineral composed of calcium (Ca²⁺) and fluoride ions (F⁻) in a 1:2 ratio. This ionic compound is known for its industrial significance due to its unique properties.

Key Points About Fluorspar Formula:

1. Chemical Structure:
   • The fluorspar formula shows that each calcium ion is surrounded by two fluoride ions, forming a stable ionic lattice.
2. Uses:
   • It is a critical raw material in the production of hydrofluoric acid and fluorine-based compounds.
   • Used as a flux in metallurgy to lower the melting point of raw materials.
   • Its optical properties make it valuable for lenses and other optical applications.
3. Physical Appearance:
   • Fluorspar often appears in vibrant colors like purple, green, or clear, depending on impurities.${\mathrm{CaF}}_2$
