Medium grade magnesia has strong reducibility, can react with boiling water to release hydrogen, and can produce dazzling white light when burning. Magnesium does not react with fluoride, chromic acid, or caustic soda, but it is easy to dissolve in and Mineral acid. Ordinary fused magnesia, magnesium can directly combine with nitrogen, sulfur, halogen, etc., and chemicals, including hydrocarbons, aldehydes, alcohols, phenols, amines, lipids, and most oils, can slightly or work with magnesium. However, the reaction with halogenated hydrocarbon under anhydrous condition is more intense (producing Grignard reagent). Magnesium can burn with carbon dioxide, so magnesium combustion cannot be extinguished with carbon dioxide extinguisher. Fused magnesia
Magnesium can interact with N? And O? Reaction, so when magnesium burns in the air, it emits dazzling white light, releases heat, and generates a white solid. The change in vinegar is the rapid emergence of bubbles, floating on the vinegar surface, and gradually disappearing. Some fireworks and flares contain magnesium powder, which utilizes the property of magnesium burning in the air to emit dazzling white light. Magnesium metal can react with most non-metals and acids; It can directly synthesize Magnesium hydride with hydrogen under high pressure; Magnesium can react with halogenated hydrocarbon to synthesize Grignard reagent, which is widely used in synthesis. Magnesium has a clear tendency to generate coordination compounds.
Magnesium is an important material in the aviation industry, and magnesium alloys are used for manufacturing aircraft fuselage, engine parts, etc; Magnesium is also used to make photographic and Optical instrument; Magnesium and its alloys have a wide range of unstructured applications; Magnesium, as a strong reducing agent, is also used in the production of titanium, zirconium, beryllium, uranium, and hafnium. In case of slight magnesium deficiency, magnesium can be supplemented by diet or oral administration, and magnesium oxide or Magnesium hydroxide can be given. In order to avoid diarrhea, it can be combined with Aluminium hydroxide glue. When oral administration is intolerable or unabsorbable, Intramuscular injection of magnesium can be used, generally 20%~50% magnesium is used. When administering magnesium intravenously, attention should be paid to the occurrence of acute magnesium poisoning to avoid sudden cardiac arrest. Therefore, avoid giving too much or too fast magnesium. In case of magnesium poisoning, inject Calcium gluconate or calcium chloride.
