Last Update:2022-01-01 09:06:34 Magnesium fluoride - Preparation Method Open Data Verified Data magnesite powder is added to excess hydrofluoric acid under stirring, and reacted at 90~95 °c to obtain magnesium fluoride, which is filtered, washed, and dried at about 105 °c, it was obtained after crushing. Last Update:2022-01-01 09:06:35 Magnesium fluoride - Introduction It shows purple fluorescence under the light, slightly soluble in dilute acid, almost insoluble in water. Rutile lattice, under electro-optic heating to show weak purple fluorescence, the crystal has a good polarization effect, especially suitable for ultraviolet and infrared spectrum. Very slightly soluble in water (18 ℃,87mg/L), slightly soluble in dilute acid (especially nitric acid). The lethal dose (guinea pig, oral) is 1.0 g/kg. It's irritating. Last Update:2022-10-16 17:28:45 Magnesium fluoride - Use Open Data Verified Data a fluorescent material used as a cathode ray screen, an inverse refractive agent for an optical lens, and a solder. It is also a flux for the manufacture of ceramics, glass, magnesium and aluminum, and a coating for lenses and filters in optical instruments. Last Update:2022-01-01 09:06:35 Magnesium fluoride - Safety Open Data Verified Data guinea pig oral LD:lOOOmg/kg, intramuscular injection of 3000mg/kg. The operator should do the necessary protection. This product is toxic. Operators should wear necessary protective equipment. The use of two layers of kraft paper bags or woven bags lined with polyethylene plastic bags. 50kg net weight per bag. The package should be marked with "drug. Belonging to inorganic drugs. Should be stored in a cool, dry warehouse. It cannot be co-stored and co-transported with food products.

Operators should wear necessary protective equipment. Use for the optical glass and ceramic industry and the electronics industry for the manufacture of ceramics, glass, co-solvent for smelting magnesium metal, coating of lenses and filters in optical instruments. Fluorescent materials for cathode ray screens, anti-refractive agents and soldering agents for optical lenses, and coating agents for titanium pigments. production method magnesium carbonate method in a lead-lined reactor containing an excess of hydrofluoric acid, magnesite pulp is added under agitation, the reaction was carried out at 90-95 °c. The magnesium fluoride produced by the reaction was filtered, washed, dried at about 105 ° C., and then pulverized to obtain a finished magnesium fluoride. MgCO3 2HF → MgF2 H2O C02
