magnesium oxide

Magnesium oxide is a strongly alkaline metal oxide that can modify HZSM-5 molecular sieve. The main functions of magnesium oxide modification are: ① Reduce the acidic strength of HZSM-5 molecular sieve, thereby reducing the reaction of methanol dehydration to produce methane and ethylene as by-products. ② Increase the alkaline strength of HZSM-5 molecular sieve, thereby […]

Market size According to MarketsandMarkets, the global spherical magnesia market size will be US$1.15 billion in 2022 and is

Recently, the ISO certification audit expert group audited and certified the quality, environment, and occupational health and safety management systems of Hebei Messi Biology Co., Ltd. During the five-day review, the expert group conducted detailed exchanges and guidance on the system operation of six departments and two workplaces of Hebei Messi Biology Co., Ltd. Through

Hebei Messi Biology Co., Ltd. stated that flame retardant materials on the market generally include magnesium hydroxide, aluminum hydroxide, etc. However, the flame retardant effects of magnesium carbonate and magnesium oxide are also very good. According to different volumes, magnesium oxide is classified into light magnesium oxide and heavy magnesium oxide. Compared with other types

A special rectification campaign for the magnesite industry in Liaoning Province has been launched. The Liaoning Province Magnesite Industry High-Quality Development Work Leading Group and the Magnesite Industry High-quality Development Work Deployment Meeting were held on December 11. According to the “Implementation Opinions of Liaoning Province on Promoting High-Quality Development of the Magnesite Industry” and

The reaction process of magnesium oxide during high-temperature annealing of grain-oriented silicon steel can be divided into three stages: Diffusion of Mg ions When the annealing temperature reaches 800-900 degrees Celsius, Mg ions begin to diffuse from the magnesium oxide coating into the interior of the silica particles. The rate of Mg ion diffusion depends

There are many methods for preparing spherical nano-magnesium oxide powder, among which the most commonly used ones are as follows: Hydrothermal method: This method is to hydrolyze a soluble magnesium oxide salt solution in a high temperature and high pressure environment to prepare nano magnesium oxide particles. The nano-magnesium oxide particles prepared by the hydrothermal

Hebei Messi Biology Co., Ltd. stated that as an important functional inorganic material, magnesium oxide is widely used in the fields of metallurgy, electronics, catalysis, ceramics, coatings, medicine, adsorption, refractory materials and optical materials. Mineral direct pyrolysis, chemical precipitation, gas phase hydration, carbonization, ammonium bicarbonate, spray pyrolysis, hydrothermal, sol-gel and other methods are used for

Hebei Messi Biology Co., Ltd. stated that the hydration of magnesium oxide is a solid-liquid heterogeneous reaction. As hydration proceeds, the magnesium oxide particles gradually shrink and generate magnesium hydroxide. The conversion process includes the following steps: (1) The magnesium oxide molecules on the surface are hydrated to form magnesium hydroxide; (2) Diffusion of magnesium

Magnesium oxide is the basic raw material for the synthesis of hydrotalcite. A large amount of magnesium required for the synthesis of hydrotalcite is provided by magnesium oxide. The main applications of magnesium oxide in hydrotalcite include the following aspects: Improve the flame retardancy of hydrotalcite: Magnesium oxide has good flame retardancy. Adding magnesium oxide
