Magnesium Oxide

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 […]

According to the requirements of the pharmaceutical and food industries for magnesium oxide, Hebei Messi Biology Co., Ltd. proposed to produce medicinal magnesium oxide by the brine-ammonia method, and the impurity ions in the brine that affect the product quality were removed by a simple method. The indicators of the obtained magnesium oxide all meet

Hebei Messi Biology Co., Ltd. stated that with the increase in China’s electrical steel production, the demand for silicon steel grade magnesium oxide has continued to increase, and the traditional process of preparing magnesium oxide using dolomite as raw material can no longer meet market demand. China is a country rich in brine resources, so

Hebei Messi Biology Co., Ltd. stated that in the past 10 years, the annual production capacity of magnesium oxide in the world has grown rapidly. It is understood that the main reason for the increase in production capacity is that in the rubber industry, the use of magnesium oxide as a vulcanization promoter has increased

Hebei Messi Biology Co., Ltd. stated that silicon steel grade magnesium oxide can improve the insulation performance of silicon steel sheets, can be used as a high temperature annealing isolation agent, can also be used to make ceramic materials and electronic materials, and is used as a dephosphorization agent, desulfurization agent, and insulating coating generator

Hebei Messi Biology Co., Ltd. stated that magnesium oxide was used to modify γ-Al2O3, a common carrier of sulfur-resistant shift catalyst, and CoO-MoO3/γ-Al2O3+MgO sulfur-resistant shift catalyst was studied by using pressurized “original particle size” evaluation device and XRD, SEM and other analytical test methods. The results show that adding an appropriate amount of magnesium oxide

Silicon steel sheets are called electric porcelain steel sheets abroad. Their main purpose is to make motor cores and transformer cores. In order to meet the requirements of the electrical and physical properties of the core, the silicon steel sheets undergo a high-temperature annealing process of 1200-1250 degrees Celsius during the manufacturing process of oriented

Hebei Messi Biology Co., Ltd. has found that the surface coating and modification of magnesium oxide improves the structural stability of magnesium oxide without reducing its useful specific capacity. The specific capacities of lithium cobalt oxide after magnesium oxide surface coating and modification when charged to 4.3.4.5.4.7V (Li+/Li) are 145, 175 and 210mAh/g respectively. The

Hebei Messi Biology Co., Ltd. stated that ultra-high-purity magnesium oxide is a new functional fine inorganic material, which is widely used in many fields such as electronic components and advanced ceramic materials; for example, magnesium oxide dielectric protective film is a key component in the new generation of plasma flat panel displays (PDPs). Its performance

Hebei Messi Biology Co., Ltd. stated that there are many methods for preparing nano magnesium oxide. Magnesium nitrate hexahydrate is used as a precursor, and nano magnesium oxide powder is synthesized by citric acid sol-gel method. Characterization and comparison with magnesium oxide powder prepared by precipitation method show that the sol-gel method has the advantages
