Magnesium fluoride is a halogen element fluorine and magnesium metal compounds, a colorless square crystal or powder, odorless, soluble in water and alcohol, slightly soluble in dilute acid, soluble in nitric acid. Under electric heating are weak fluorescent purple, the polarization of the crystal has a good effect, especially suitable for uv and ir spectra. There are toxic.
Use optical lens coating. The optical coating on a layer of magnesium fluoride membrane layer, can reduce the camera interface of the incoming light reflex, reduce the halo, improve the quality of imaging. Magnesium fluoride also used in ceramic, electronics industries; Manufacturing ceramics, glass; Metallurgy magnesium flux; The fluorescent material of cathode ray screen; Flux, etc.
Warm reminder: although magnesium fluoride chemical properties is stable, does not decompose heating, even strong electrolytic hard to separation, so generally there is no harm to human body, but long-term exposure will cause certain harm to human body, such as: cause fluorine spot tooth and skeletal fluorosis. If direct oral magnesium fluoride, can cause salivation, nausea, vomiting, diarrhea and abdominal pain, followed a tremor, coma, can die from respiratory paralysis.
