Hebei Messi Biology Co., Ltd. stated that special ceramics are made of aluminum oxide, magnesium oxide and other compounds, which are crushed, shaped, and fired at high temperature by traditional or special methods. Some of them need to be machined or polarized after firing to meet the precision requirements for size and shape, or to make the product have specific ferroelectric properties. Special ceramics can be roughly divided into two categories: structural ceramics and functional ceramics. Structural ceramics far exceed traditional ceramics in terms of strength, hardness, wear resistance, heat resistance, and corrosion resistance. Functional ceramics have special properties…

Hebei Messi Biology Co., Ltd. said that magnesium oxide inhibits the flow of polyhalide lithium salt electrolytes at high temperatures, ensuring the safety of thermal batteries. The physical properties of different types of magnesium oxide materials were compared and analyzed, and their adsorption properties for lithium salt electrolytes were analyzed through overflow experiments. The results showed that MgO materials with small tap density and large specific surface area exhibited the optimal adsorption performance. The single pole piece of the thermal battery is composed of heating material, positive electrode, electrolyte and negative electrode. When the battery is activated, the heating…

A low-grade cobalt ore in the Democratic Republic of Congo (DRC) in Africa is used as raw material. The contents of cobalt, manganese, iron, alumina and magnesia in the low-grade cobalt ore are 0.26%, 0.51%, 1.73%, 6.37% and 5.54% respectively. Adopt this method cobalt recovery rate > 80%, the cobalt content > 31% of cobalt hydroxide product. In the high-efficiency cobalt recovery industrial test of the low-grade cobalt ore, the following steps are sequentially included. The first step of leaching: add water to adjust the leached ore to a pulp mass percentage concentration of 35%, add concentrated sulfuric acid…

According to the requirements of the pharmaceutical and food industry for magnesium oxide, Hebei Messi Biology Co., Ltd. proposed to use the brine-ammonia method to produce medicinal magnesium oxide, and remove the impurity ions in the brine that affect the product quality with a simple method. Up to the national standard. Using magnesite ore, ammonium bicarbonate, and sulfuric acid as raw materials, the metathesis method is adopted, the mother liquor is fully circulated, the neutralization, dissolution, ammonia absorption, and metathesis reaction mechanisms are effectively used, and the process conditions are optimized. , establish a production quality management assurance system,…

Messi Biology said, with the increase of electrical steel production in China, the demand of silicon steel grade magnesium oxide is increasing, the traditional process of preparing magnesium oxide from dolomite is unable to meet the market demand. China is a country rich in brine resources, therefore, it becomes more and more important to study how to resourcefully and comprehensively utilize the salt lake resources. The silicon steel grade magnesium oxide is a kind of coating material for the preparation of oriented silicon steel, mainly used in the high temperature annealing treatment stage of oriented silicon steel, playing the…
