Magnesium oxide is an inorganic compound with the chemical formula MgO. It is an oxide of magnesium and an ionic compound. It is a white solid at room temperature. Magnesium oxide exists in the form of periclase in nature and is a raw material for magnesium smelting.
Magnesium oxide has high fire resistance and insulation properties. After being burned at high temperatures above 1000 ℃, it can transform into crystals. When it reaches 1500-2000 ° C, it becomes dead burned magnesium oxide (magnesia sand) or sintered magnesium oxide.
Magnesium oxide (chemical formula MgO) is a common inorganic compound that belongs to alkaline oxides and has various properties and uses:
Magnesium oxide is a stable white solid at room temperature and pressure, but it forms magnesium hydroxide in the presence of water. Magnesium oxide has high fire resistance and insulation properties. It can transform into crystals at high temperatures above 1000 ℃, and become dead burned or sintered magnesium oxide when it reaches 1500-2000 ° C. These characteristics make magnesium oxide widely used in the production of high-temperature ceramics, refractory materials, and other fields.
Magnesium oxide is used in the healthcare industry to produce drugs and medical materials, such as as as antacids and laxatives, which help alleviate excessive stomach acid and digestive system diseases. It can also be used as a food additive to regulate the pH, color, and quality of food. In the food industry, magnesium oxide is also used to supplement magnesium, which helps regulate nerves and blood sugar, and extends the shelf life of vegetables.
Magnesium oxide is also widely used in the industrial field, such as as as a cleaner, vanadium suppressant, and desulfurizer in lubricating oil, to improve the density and rheological properties of lubricating films, reduce environmental pollution. In the production of silicon steel, magnesium oxide is used to improve the insulation performance and magnetic conductivity of materials, and is also applied in electronic materials, ceramic materials, and other fields.
In addition, magnesium oxide can also be used to prepare highly functional fine inorganic materials, electronic components, inks, harmful gas adsorbents, etc. It has the characteristics of being non-toxic and environmentally friendly, and is a new type of environmentally friendly halogen-free flame retardant.
