Natural hydromagnesite (hydromagnesite compound flame retardant) Hydromagnesite is a new type of high temperature resistant flame retardant, which can release water and CO2 successively under the action of heat. These decomposition and release processes can absorb a lot of heat, thereby reducing the flame retardant. The temperature of the flame on the surface of the […]

As a common hydrated magnesium-rich carbonate mineral, hydromagnesite [Mg5(CO3)4(OH)2·4H2O] can be used as a high-quality mineral-type flame-retardant filler in the field of polymer flame-retardant. Studies have shown that hydromagnesite mainly occurs in carbonate-type saline lakes and Quaternary lacustrine strata, and was also found in the lacustrine deposits of Jezero Crater on Mars, and the Mg/Ca
The thermal decomposition method is to prepare magnesium oxide by calcining magnesium carbonate (magnesite)) and magnesium hydroxide (brucite) at high temperature, the type and particle size of the roasting precursor, and the process conditions of calcining (roasting atmosphere, gas flow rate, etc.) and heating rate, etc.) affect the surface morphology and surface properties of magnesium
