The article discusses magnesium fluoride (MgF2) as a spectral reagent, highlighting its optical properties, chemical interactions, and wide-ranging applications across industries such as pharmaceuticals, food, chemicals, environment, and electronics.

Magnesium fluoride is off white crystal, It is a positive birefringence crystal with extremely high resistance to mechanical and thermal shock and radiation.

FOSHAN NANHAI SHUANGFU CHEMICAL CO., LTD is one of the manufacture of high quality Magnesium fluoride, supply long term production and delivery of this product all over the world.

Magnesium fluoride is an inorganic, white crystalline compound, which is transparent over a wide range of wavelengths. MgF2 can be found naturally as the rare mineral sallaite and artificially prepared from magnesium oxide with hydrogen fluoride. The chemical’s transparency makes it a suitable ingredient for optic lenses, polarizing prisms, and ceramics.
