Magnesium Carbonate

Hebei Messi Biology Co., Ltd. stated that adding magnesium carbonate to lithium batteries can improve the conductivity of the battery, prolong the service life of the battery, slow down the self-discharge of the battery, improve the storage performance, and increase the utilization rate of the active material of the battery. However, the performance of battery […]

Messi Biology said that at present, domestic high-grade magnesium carbonate mainly relies on imports, and the market gap is relatively large. The annual demand for high-purity magnesium carbonate in China is nearly 100,000 tons, while the domestic production is only about 10,000 tons. There is a large market gap for some varieties such as Pharmaceutical

Anhydrous magnesium carbonate exists in the form of magnesite in nature, and complete isomorphism can be formed between mgco3 and feco3, that is, mg2+ and fe2+ in the crystal structure can replace each other due to their similar properties, and their crystal physical properties vary with the two The number of elements changes in a

Hydrated basic magnesium carbonate, also known as light magnesium carbonate, is a white crystal or powder, loose in texture, stable in the air, and slightly different in chemical composition due to different preparation methods and conditions. Its relative density is small, and it can be used as rubber, Additives for plastic products, also have the

At present, there are brine soda ash method and brine ammonium bicarbonate method in domestic production of basic magnesium carbonate with brine, but there is no report on the production of food grade basic magnesium carbonate. The production process of the brine soda ash method is simple, the investment in equipment is small, and the

A method for preparing industry-grade basic magnesium carbonate for battery cathode materials from salt lake brine, which includes conversion coupling, solid-liquid separation, slurry washing, dehydration, drying and packaging steps, firstly mixing lithium carbonate electrodialysis separation tail liquid with lithium carbonate conversion tail liquid , carry out three-stage overflow-continuous conversion reaction; Then the mixed material liquid

Als Rohmaterial wurde das durch Kalzinierung von Magnesia-Erz gewonnene leicht gebrannte Magnesiumoxidpulver verwendet, die Magnesiumsulfatlösung wurde durch Säureauflösung gewonnen und die basischen Magnesiumcarbonatprodukte wurden durch die Ammoniumbicarbonat-Fällungsmethode hergestellt. Unter unterschiedlichen Pyrolysebedingungen wurden Produkte mit unterschiedlichen Molekülstrukturen gewonnen. Dabei wurde festgestellt, dass die Molekülformel der bei 60–90 °C gewonnenen Produkte als Mg5(CO3)4(OH)2–8H2O ausgedrückt werden konnte, während

Eine praktische Methode zur Synthese von rosafarbenen, porösen Mikrokugeln aus alkalischem Magnesiumcarbonat (4 MgCO3 · Mg (OH)2 · 4 H2O). Diese Methode ist in drei Schritte unterteilt: Synthese von Wassercarbonat ( MgCO3 · 3 H2O) für den Vorderradantrieb und Herstellung durch Erhitzen in Wasser. Die Synthese des Vorderradantriebs erfolgt durch die Methode der Kristallmischung, wodurch
