Magnesium chloride is one of the substances that are abundant in brine and have high added value. In addition to its own use, other magnesium products produced from magnesium chloride are also very widely used. High purity magnesium oxide is one of them. At present, there are many methods to produce high purity magnesium oxide, […]

Messi Biology said, activity is not only an important physical and chemical property of magnesium oxide, but also an important index to measure the magnesium oxide used in rubber and plastic industries. Activated magnesium oxide is mainly used as activator and accelerator of butyl rubber, neoprene rubber, fluorine rubber, nitrile rubber, or one of the

Messi Biology indicated that lithium/magnesium oxide catalysts and lithium/magnesium oxide nanocatalysts were prepared by primary wet impregnation and sol-gel method, respectively. The catalytic performance of the two lithium/magnesium oxide catalysts was compared for the methane oxidation coupling reaction. The characterization was carried out by X-ray diffraction, BET adsorption and transmission electron microscopy. The catalysts were

Messi Biology said, Hydromagnesite is a rare natural hydrated alkaline magnesium carbonate in the world, commonly known as \”magnesium white\”. Its appearance is white block, earthy luster, \”snow-white\” or \”white-flower\” called, density is 2.24g.cm3, Mohs hardness is 3.5, melting point is 730 ℃, is monoclinic crystal structure 123l. The ore is porous and small bubbles

In the epoxy resin neutron shielding material research and development production, more or less will use magnesium oxide \\ magnesium hydroxide products, and compared to ordinary products, shielding materials require more stringent indicators, Hebei Messi Biology Co. In the epoxy resin neutron shielding material development and production of the preferred, non-halogen inorganic flame retardant for

Messi Biology said, nano magnesium hydroxide molecular formula Mg(OH)2, white microfine powder, non-toxic, tasteless, non-corrosive, relative density 2.36, refractive index 1.561, 350 ℃ began to decompose, 430 ℃ when the decomposition is rapid, 490 ℃ when all decomposition, soluble in strong acid solution and ammonium salt solution, insoluble in water. Compared with ordinary magnesium hydroxide

Hebei Messi Biology Co., Ltd Tibet Nagqu Bango Lake water magnesite (4MgCO3-Mg(OH)2-4H2O) is a natural alkali carbonate mineral with rich reserves, its texture is pure, white color, low impurity content, is a high quality mineral raw material for preparing magnesium products such as flame retardant, active magnesium oxide, heavy alkali magnesium carbonate, nano magnesium hydroxide.

Magnesium sedimentation wastewater treatment In addition to calcium ions, the liquid after magnesium precipitation basically does not contain other metal ions, but the pH value is higher than 11, can not be directly discharged. Part of the magnesium wastewater can be used for lime slurry, and the remaining wastewater can be neutralized and discharged to

About 20% of the cobalt is still not recovered in one section of the cobalt precipitation process, and this process uses lime neutralization and precipitation to recover the cobalt in the liquid after one section of cobalt precipitation: Ca(OH)2+CoSO4=Co(OH)2↓+CaSO4 At the same time, under the alkaline environment, part of magnesium sulfate will react with lime

After the initial purification of the post-removal liquid and magnesium oxide slurry under certain conditions, that is, to generate cobalt hydroxide precipitation, the reaction is as follows: Mg(OH)2+CoSO4=Co(OH)2↓+MgSO4 In order to get high grade cobalt hydroxide product and high cobalt recovery, the experiment of active magnesium oxide usage was carried out to find out its
