Hebei Messi Biology Co., Ltd. stated that the production of magnesium oxide by dolomite carbonization method generally adopts normal pressure and low temperature (≤25%) carbonization method to separate calcium and magnesium to produce light magnesium carbonate, and then calcine to produce light magnesium oxide. The temperature changes greatly in the whole process and the energy […]

With the development of China’s electric power industry, there are higher requirements for the iron cores of transformers, motors and generators. Many large steelmaking enterprises in China have established or are establishing production lines for silicon steel sheet. With the increase of silicon steel production, the demand for silicon steel grade magnesia with higher purity

1. The effect of the amount of magnesium oxide added on the content of magnesium oxide in the FCC catalyst It is the comparison between the amount of magnesium oxide added and the content of magnesium oxide in the FCC catalyst. Magnesium oxide addition does not have a linear relationship with the magnesium oxide content

Summary By designing and preparing in situ synthesized nano magnesium oxide doped crab shell-based hierarchical porous carbon (n-MgO@CSHPC), while efficiently immobilizing polysulfides, it can ensure good contact between polysulfides and conductive structures, and realize polysulfides. The balance of adsorption and reuse can improve the utilization rate of active materials and improve the electrochemical performance of

Magnesium oxide is mainly used in brominated butyl rubber plugs and halogenated butyl rubber plugs, and its main functions are vulcanization accelerators and acid absorption. Requirements for magnesium oxide: In general, both light and active magnesium oxide are used. Light magnesia requires MgO ≥ 93-95%, CaO ≤ 1.5%, apparent specific volume ≥ 5ml/g, fineness 325

At present, the raw materials for preparing silicon steel grade magnesium oxide mainly include magnesite (MgCO3), dolomite (CaCO3 MgCO3), magnesium-containing industrial by-products, seawater or salt lake brine (MgCL2), etc. The production process can be divided into basic magnesium carbonate Magnesium ore carbonization method and ammonium bicarbonate method as intermediate, brine pyrolysis method with basic magnesium chloride
