If customers want to purchase qualified pharmaceutical and food-grade magnesium oxide products, we need to start from two aspects. First, see whether the magnesium oxide manufacturer has a qualification certificate issued by the state, such as GMP pharmaceutical production license, food production license, etc.; second, see whether the content of magnesium oxide can meet the […]

Hebei Messi Biology Co., Ltd. stated that after the cobalt concentrate is precipitated with magnesium oxide, it can be made into cobalt intermediates (generally crude cobalt hydroxide) or directly made into cobalt salt products such as cobalt chloride and cobalt sulfate. Therefore, the use of active magnesium oxide is of utmost importance, and the quantitative

Hebei Messi Biology Co., Ltd. stated that magnesium oxide and magnesium carbonate are important additives in rubber products. The amount of magnesium oxide and magnesium carbonate used in many foreign brand tires is much higher than the domestic average level, generally about 3-7 parts. After the increase of magnesium oxide and magnesium carbonate by 30%-70%,

Customers often ask about the difference between food-grade granular magnesium oxide and powdered magnesium oxide. Hebei Messi Biology Co., Ltd. briefly introduces the two. First of all, the difference between granular magnesium oxide and powdered magnesium oxide is in the production process. Generally, there will be no difference in content, heavy metals, calcium, iron and

Hebei Messi Biology Co., Ltd. stated that magnesium chloride is one of the substances with abundant content and high added value in brine. In addition to its own utilization value, other magnesium products produced with magnesium chloride as raw material also have very wide applications. High-purity magnesium oxide is one of them. At present, there

Hebei Messi Biology Co., Ltd. stated that activity is not only an important physical and chemical property of magnesium oxide, but also an important indicator for measuring magnesium oxide used in rubber, plastic and other industries. Active magnesium oxide is mainly used as an activator and promoter for butyl rubber, chloroprene rubber, fluororubber, and nitrile

In 2024, the price of magnesium oxide will remain high, and international magnesium oxide manufacturers will raise their sales prices. Many domestic magnesium oxide manufacturers have already raised their prices, with an increase of more than 50%. It is expected that the price of magnesium oxide will remain high for a period of time in

Hebei Messi Biology Co., Ltd. stated that lithium/magnesium oxide catalysts and lithium/magnesium oxide nanocatalysts were prepared by incipient wetness impregnation and sol-gel methods, respectively. The catalytic performance of the two lithium/magnesium oxide catalysts for methane oxidative coupling reaction was compared. Characterization was performed by X-ray diffraction, BET adsorption and transmission electron microscopy. The catalysts were

Hebei Messi Biology Co., Ltd. stated that the current cobalt product of the cobalt salt plant is crude cobalt carbonate, which is precipitated with sodium carbonate, and the post-precipitation liquid is directly discharged. The defect of this process is that there is a large amount of sodium sulfate in the discharged waste liquid. The wastewater
