Hebei Messi Biology Co., Ltd. stated that magnesium oxide can be used as raw material for optical glass and microcrystalline glass. Magnesium oxide single crystals for optical components are also made of high-purity magnesium oxide. Magnesium oxide for optical glass has the characteristics of high purity, high specific gravity, and few calcium and iron impurities.

Hebei Messi Biology Co., Ltd. stated that in order to overcome the defects of poor catalytic activity and poor stability of ruthenium-based ammonia decomposition hydrogen production catalysts in the prior art under medium and low temperature conditions, a ruthenium-based ammonia decomposition hydrogen production catalyst is provided for the application of ammonia decomposition to prepare carbon-free

Hebei Messi Biology Co., Ltd. stated that adding magnesium oxide to microcrystalline glass can adjust the crystallization temperature of glass. At low temperatures, it can alleviate the decrease in glass viscosity, and at high temperatures, it can accelerate the increase in viscosity. Excessive iron and chloride in magnesium oxide will affect the color of glass.

Hebei Messi Biology Co., Ltd. said that silicon steel grade magnesium oxide needs to meet the quality technical indicators of MgO>98%, CaO<0.5%, and Cl<0.02%. The impurity CaO will be hydrated into Ca(OH)2 in the slurry and then coated on the surface of the steel plate to absorb CO2 in the air to form CaCO3. When

Hebei Messi Biology Co., Ltd.. stated that cobalt, nickel and magnesium often coexist in the sulfuric acid leaching solution of nickel oxide ore. The saponification P507 process is usually used to separate cobalt and nickel. This process has problems such as the introduction of impurity ions, long process flow and wastewater discharge. The magnesium oxide

Hebei Messi Biology Co., Ltd. stated that the production of silicon steel grade magnesium oxide mainly uses seawater brine and minerals as raw materials. When using liquid raw materials for production, alkaline solution is first used as a precipitant to precipitate magnesium, and then further prepare magnesium oxide. my country mainly uses the brine-ammonium carbonate
