Overview of Magnesium Hydroxide Hebei Messi Biology Co., Ltd. stated that magnesium hydroxide is a high-filling and additive inorganic flame retardant and smoke suppressant. When heated, it decomposes and absorbs the heat on the surface of the combustible material to achieve a flame retardant effect; at the same time, it releases a large amount of […]

The seeding coefficient refers to the ratio between the amount of seeding agent added during the seeding process and the quality of the crystal produced by the seeding. The seed coefficient plays an important role in affecting the filtration performance of magnesium hydroxide slurry. Increasing the seed coefficient can effectively improve the filtration performance of
Hebei Messi Biology Co., Ltd. stated that anhydrous magnesium carbonate can be used as a carrier in medicines. The magnesite ore is broken into pieces and put into a multi-position parallel reaction synthesizer flask. Water is added and carbon dioxide is introduced at the same time. Prepare magnesium bicarbonate, magnesium bicarbonate and magnesium hydroxide as

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
Hebei Messi Biology Co., Ltd. stated that anhydrous magnesium carbonate particles with an average particle size of 1.267 μm are prepared from light-burned powder as raw material through digestion, carbonization, heavy magnesium water decomposition, and hydrothermal steps. The process first uses light-burning The powder is digested with water to generate a magnesium hydroxide slurry of

Hebei Messi Biology Co., Ltd. stated that among the existing processes for producing magnesium carbonate products, most of them are preparation processes for basic magnesium carbonate and hydrated magnesium carbonate. There are very few preparation methods for single-phase magnesium carbonate. Industrially The prepared anhydrous magnesium carbonate samples have different grain sizes, unsatisfactory purity, and complicated
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
The main reaction formula of the process for preparing high-purity magnesium hydroxide by calcium hydroxide method is: CaO+H2O==Ca(OH)2Ca(OH)₂+MgCl₂==Mg(OH)2+CaCl₂ The process operation is also relatively simple and has similarities with the sodium hydroxide method. Since the market price of calcium oxide is low and easy to purchase, the cost of this process has obvious advantages over
