Hebei Messi Biology Co., Ltd. stated that hydromagnesite is a natural mineral with a chemical composition of 4MgCO·Mg(OH)·4H2O, which is a superior mineral resource in my country. When hydromagnesite is calcined, magnesium carbonate decomposes, releasing carbon dioxide gas and generating magnesium oxide at the same time. The most important factors affecting the activity of magnesium […]
Hebei Messi Biology Co., Ltd. stated that high-performance magnesium oxide with specific reactivity, particle size and flow characteristics can be used to manufacture transformer silicon steel sheets with grain orientation. During the annealing process, the steel is treated with a magnesium oxide coating to form a glass-ceramic film (forsterite). The insulating properties of this film
Hebei Messi Biology Co., Ltd. stated that magnesium hydroxide is an important inorganic material and is widely used in daily life. Magnesium hydroxide can be used to neutralize acidic wastewater, absorb heavy metals in water, serve as a wastewater decolorizer, and absorb sulfur dioxide in flue gas. As a green inorganic flame retardant, magnesium hydroxide
Study on Preparation of Flame Retardant Hexagonal Flake Magnesium Hydroxide from Brine Read More »
Hexagonal magnesium hydroxide flame retardant has the advantages of smoke suppression, green and environmental protection, but due to its low flame retardant efficiency, it often requires a large filling amount when used in polymer substrates. Because magnesium hydroxide, as an inorganic powder, has the characteristics of hydrophilicity and oleophobicity and high polarity, it is not

Hebei Messi Biology Co., Ltd. stated that a method for preparing industrial-grade basic magnesium carbonate for battery positive electrode material from salt lake brine includes conversion coupling, solid-liquid separation, slurry washing, dehydration, drying and packaging steps. First, the lithium carbonate electrodialysis separation tail liquid and the lithium carbonate conversion tail liquid are mixed to perform
Hebei Messi Biology Co., Ltd. stated that magnesium oxide inhibits the flow of polyhalide lithium salt electrolytes at high temperatures, ensuring the safety of thermal batteries. The physical properties of different types of magnesium oxide materials were compared and studied, and their adsorption performance on lithium salt electrolytes was analyzed through overflow experiments. The results
Hebei Messi Biology Co., Ltd. stated that a low-grade cobalt ore in the Democratic Republic of the Congo in Africa was used as raw material. The cobalt, manganese, iron, aluminum oxide and magnesium oxide contents of the low-grade cobalt ore were 0.26%, 0.51%, 1.73%, 6.37% and 5.54% respectively. The cobalt recovery rate of this method
