Hebei Messi Biology Co., Ltd. stated that magnesium is a widely used metal in the modulation of acidity of HZSM-5 molecular sieve. The acidity of the nano-HZSM-5 molecular sieve is adjusted by magnesium oxide modification, using XRD, aluminum solid magic angle spinning nuclear magnetic resonance (AI MAS NMR), N₂ adsorption/desorption, ammonia-temperature programmed desorption (NH3-TPD) and […]

Magnesium oxide is a very common alkaline oxide and the main raw material for the production of magnesium hydroxide and magnesium metal. In the application of ceramic materials, magnesium oxide has a melting point as high as 2800°C and has some special and excellent properties. Therefore, it is also quite popular in the field of

The dry granulation process of pharmaceutical and food grade magnesium oxide refers to mixing magnesium oxide powder prepared by wet method with auxiliary agents such as binders, dispersants, lubricants, etc. under anhydrous or low-moisture conditions, and then granulating the powder through granulation equipment. A method of producing particles of a certain particle size and shape.

Technical field: The present invention relates to a process method for preparing high purity magnesium oxide, and in particular relates to a method for preparing high purity magnesium oxide with low chlorine root content. Background Technology: Magnesium oxide is an ionic compound, which is a white solid at room temperature, and high purity magnesium oxide

Magnesium oxide is generally divided into high-purity magnesium oxide and active magnesium oxide. Different models of magnesium oxide have different uses. Let’s take a look at the differences between high-purity magnesium oxide and active magnesium oxide. High-purity magnesium oxide generally refers to content greater than 98%. Under high-temperature conditions, high-purity magnesium oxide has good electrical

The main preparation processes for magnesium oxide for cover glass are as follows: 1. Magnesium hydroxide method: Using natural dolomite or magnesite as raw materials, magnesium hydroxide is obtained through calcination, digestion, filtration, drying, calcination and other processes, and then high-temperature melting, cooling, crushing, sieving and other processes are used to obtain magnesium hydroxide. magnesium.
