Low-calcium white magnesia
- Commodity name： Low-calcium white magnesia
- Product Description
-
Magnesium chloride is an inorganic compound with the chemical formula MgCl2 and a molecular weight of 95.211. It appears as colorless flaky crystals, is slightly soluble in acetone, and soluble in water, ethanol, methanol, and pyridine. It is deliquescent and fumes in moist air, and sublimes when heated to white heat in a hydrogen stream. Magnesium chloride is mainly found in the salt lakes of Qaidam Basin in China. The Qarhan Salt Lake National Mining Park in Golmud, Qinghai, is the largest natural salt lake and the largest soluble potash and magnesium salt deposit in China, as well as a world-class natural laboratory for studying the formation of potash and magnesium salt deposits. The magnesium chloride reserves amount to 1.65 billion tons.
Product Uses
1. Metallurgical Industry: Used as a binder for manufacturing refractory materials and furnace linings; it is also a raw material for producing No. 2 solvent and smelting metallic magnesium.
2. Chemical Industry: Mainly used to produce various magnesium salts such as magnesium oxide, magnesium hydroxide, magnesium carbonate, and as a solid ignition agent for firecrackers; also used as a raw material for antifreeze agents.
3. Building Materials: Can be combined with magnesium oxide (periclase MgO) to make hard, corrosion-resistant magnesium oxychloride cement; can also be used to produce artificial marble, magnesia tiles, flooring, ceilings, decorative panels, fireproof boards, greenhouse supports, partition boards, magnesia manhole covers, bathtubs, door and window frames, solar cookers, biogas digesters, magnesia crafts, and portable houses.
4. Transportation Industry: Used as a road de-icing and snow-melting agent; it melts ice quickly, has low corrosiveness to vehicles, and is more effective than sodium chloride.
5. Medicine: Magnesium chloride can be processed into "halogen dry" for medicinal use.
6. Agriculture: Can be used to produce magnesium fertilizers, potassium-magnesium fertilizers, and cotton defoliants.
