The application of Foshan Shuangfu Chemical's Magnesium Fluoride (MgF₂) is:

1. Optical coatings

MgF₂ has excellent optical properties and can be used as a coating material

to enhance the reflectivity and anti-reflection properties of optical components

such as lenses, mirrors, prisms, and filters.

2. Solar cells

MgF2 is used as a passivation layer in solar cells to improve their efficiency

and reduce the surface recombination of charge carriers.

3. Fluorinating agent

MgF2 is used in the chemical industry as a source of fluorine to fluorinate

organic compounds, metals, and alloys.

4. Ceramics

MgF2 is used as a raw material in the production of ceramics,

especially those that require high thermal stability and resistance to corrosion.

5. Lubricants

MgF2 can be used as a dry lubricant in applications where conventional

liquid lubricants are not suitable, such as in high-temperature and vacuum environments.

6. Flame retardants

MgF2 is used as a flame retardant in plastics, textiles, and other materials to reduce the risk of fire.

7. Etchants

MgF2 is used as an etchant in the semiconductor industry to selectively remove layers

of silicon dioxide from silicon wafers and to create microstructures and patterns.
