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 Has been replaced by an electronic flash.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.
China's "Sanitary Standards for the Use of Food Additives" (GB2760-2014) stipulates that the amount of use depends on the normal production needs.
Sodium citrate is used as a flavoring agent and stabilizer in the food and beverage industry; as an anti-coagulant, phlegm and diuretic in the pharmaceutical industry; in the detergent industry, it can be used as a non-toxic alternative to sodium tripolyphosphate. A detergent builder; a chemically superior chelating/complexing agent that is industrially utilized for the use of sodium citrate. Also used in brewing, injection, photographic drugs and electroplating.
1, Food industry
The food industry and fisheries are used for salting and can also be used as raw materials for seasonings and as refined salt.
Adding salt to cooking dishes can remove some of the odor of the raw materials and increase the deliciousness. This is the refreshing effect of salt.
Sodium chloride is a white odorless crystalline powder. It has a melting point of 801 ° C and a boiling point of 1465 ° C. It is slightly soluble in ethanol, propanol and butane. It becomes a plasma after being miscible with butane, and is easily soluble in water. The solubility in water is 35.9 g (room temperature). NaCl is dispersed in alcohol to form a colloid, and its solubility in water is reduced by the presence of hydrogen chloride, and it is hardly soluble in concentrated hydrochloric acid. It is odorless and salty and easy to deliquesce.
Titanium carbide ceramics are typical transition metal carbides. Its bond is composed of ionic bonds, covalent bonds and metal bonds in the same crystal structure, so TiC has many unique properties. The structure of the crystal determines the basic characteristics of TiC with high hardness, high melting point, wear resistance and electrical conductivity.
Light gray, cubic crystal system, insoluble in water, with high chemical stability, almost no chemical reaction with hydrochloric acid, sulfuric acid, but soluble in aqua regia, nitric acid, and hydrofluoric acid, also soluble in alkaline In the solution of the oxide.
