As colorless crystal or powder, magnesium fluoride is an important inorganic chemical raw material. It is used as additive for electrolytic aluminum, flux for smelting magnesium metal, coating agent for titanium pigment, fluorescent material for cathode ray screen, etc. At the same time, it is also a colorless and transparent infrared optical material with wide transmission range and high transmittance, which can be used to make optical prism, lens and window element in infrared optical system.
Due to the different requirements for the quality of magnesium fluoride in various fields, the preparation methods are also different. The raw materials for industrial production of magnesium fluoride mainly come from magnesite and salt lake brine, which are suitable for large-scale industrial production, while the raw materials for the laboratory preparation of high-quality magnesium fluoride come from finished magnesium salt.
At present, the research direction of magnesium fluoride preparation mainly includes the following aspects:
First, on the basis of ensuring a certain purity of magnesium fluoride, further improve the production process and reduce the production cost;
Secondly, the finished magnesium fluoride particles should have better dispersion and more uniform particle size distribution to ensure good optical properties;
In addition, some new fields, such as magnesium fluoride nano-antibiotic film and magnesium fluoride nanotubes, have also been gradually developed and utilized. Research on the properties and development of magnesium fluoride magnesium fluoride is colorless crystal or powder, and is an important inorganic chemical raw material. Used as additive for electrolytic aluminum, flux for smelting magnesium, titanium In the production of aluminum, aluminum fluoride is used as an electrolytic bath component to reduce the melting point and improve the conductivity of the electrolyte. Used to inhibit fermentation in alcohol production Magnesium fluoride has a low refractive index and can form a wide band gap with high refractive index materials. It can be used as a low refractive index material in photonic crystals Mix magnesium fluoride powder and high-purity PbF2 powder evenly, load the crucible clamp, put the crucible clamp on the crucible base, install the heating body, and adjust the bottom of the crucible
