magnesium oxide

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

Hebei Messi Biology Co., Ltd. stated that domestic cellulose acetate production mainly uses imported high-purity magnesium oxide from foreign companies, and then gradually uses high-purity magnesium oxide from magnesite in Northeast China as a substitute. In 2017, with the increase in environmental protection efforts, magnesite in Northeast China was banned from mining due to dust

Hebei Messi Biology Co., Ltd. stated that magnesium acetate solution is a terminator for two important reactions in cellulose acetate production, namely substitution reaction and hydrolysis reaction. In cellulose acetate production, magnesium oxide and acetic acid solution reaction process are usually used to prepare magnesium acetate solution of specified concentration. MgO+2CH3COOH→Mg(CH3COO)2+ H2O In production, a

Hebei Messi Biology Co., Ltd. stated that nano magnesium oxide (MgO) is a new type of high-functional fine inorganic material. Due to its fine particles, it has special functions such as heat, light, electricity, mechanics and chemistry that are different from the bulk material. Since nano magnesium oxide is an alkaline oxide, it has a

Hebei Messi Biology Co., Ltd. stated that brown sugar is the end product of sugar production, with many impurities, high color value, and about 90% sugar. The purification of sugar juice is an important process for making high-quality sugar. Using activated carbon and macroporous resin as adsorbents to decolorize and remove impurities from sugar juice

Hebei Messi Biology Co., Ltd. stated that nano-magnesium oxide prepared by chemical method has excellent properties such as high purity, small particle size, large specific surface area, high hardness, high reaction activity, strong adsorption and good low-temperature sintering, and can be used as an adsorbent for environmental pollution control. This study conducted a systematic study
