Magnesium oxide is commonly known as bitter soil, also known as magnesium oxide. Magnesium oxide is a basic oxide and has the property of a basic oxide. It is a gelling material. White powder (light yellow is magnesium nitride), odorless, tasteless, non-toxic, is a typical alkaline earth metal oxide, chemical formula MgO. A white powder having a melting point of 2852 ° C, a boiling point of 3600 ° C and a relative density of 3.58 (25 ° C).

Magnesium oxide is divided into light magnesium oxide and heavy magnesium oxide. Lightweight and loose, white amorphous powder. Odorless, tasteless and non-toxic. The density is 3.58 g/cm3. Hard to dissolve in pure water and organic solvents, the solubility in water increases due to the presence of carbon dioxide. Soluble in acid, ammonium salt solution. It is converted into crystals by high temperature burning. In the case of carbon dioxide in the air, it forms a double salt of magnesium carbonate.
Magnesium gluconate (chemical formula: MgC12H22O14) is a magnesium salt of gluconic acid. White or grayish white odorless fine powder. Dissolved in water. It is obtained by dissolving magnesium oxide or magnesium carbonate in gluconic acid. Used as a nutritional supplement, buffer, curing agent, etc.
Oral administration of this product can increase the blood magnesium concentration and maintain the blood magnesium concentration after intravenous magnesium sulfate, for the treatment of pregnancy-induced hypertension syndrome.
Magnesium stearate is a white fine powder with no sand; it has a slight odor; it has a slippery feel when it comes into contact with the skin. This product is insoluble in water, ethanol or ether, and is mainly used as a lubricant, anti-adhesive agent and glidant. It is especially suitable for granulation of oils and extracts, and the prepared granules have good fluidity and compressibility. Used as a flow aid in direct compression.
The atomized magnesium alloy powder is obtained by centrifugally atomizing the magnesium alloy ingot after being melted at a high temperature, and then rapidly cooling at a low temperature to cause the alloy droplet to condense into a spherical shape.
Magnesium powder, silvery white metal powder, lively metal, wet and flammable. It produces intense white light when burned and gives off high heat. Hydrogen reacts with water or moisture, releasing a large amount of heat, causing burning or explosion.
Magnesite is a magnesium carbonate mineral that is the main source of magnesium. After the solution containing magnesium acts on calcite, it will turn calcite into magnesite, so magnesite also belongs to the calcite family. Magnesium-rich rocks also change into magnesite. Magnesite often contains iron, which is the result of iron or manganese replacing magnesium. Magnesite is white or off-white with a glassy luster, and iron-containing magnesite will appear yellow to brown. If the crystal is grainy, it is massive if it does not show crystals.
Because magnesium powder emits intense light when burned, early camera flashes used light from burning magnesium powder. Early flashlights were also known as spotlights (this name is still visible in some places to date), and the disadvantage of ordinary spotlights is that they can only be used once. Has been replaced by an electronic flash. Electronic flashlights are used on optical cameras and digital cameras. Also used for fireworks, electric welding rods, steel desulfurization.
Magnesium powder is flammable and explosive, and brings high temperature and glaring light when burning. Therefore, Magnesium powder is wisely used in such scientific area as war industry and aviation industry. The chemical performance of Mg is very active, which is mostly used in metallurgical industry. Mg powder can sever as desulfurizer or cleaning agent for steel-making industry and casting of non-ferrous metals, and reducer for production of rare metal. In chemical industry, Mg powder can be used as dehydrant for organic compound or to directly make organic compound of Mg.
