Magnesite is a magnesium carbonate, its chemical formula is magnesium carbonate (MgCO3), theoretical composition: MgO47.81%, CO252.19%, density 2.9-3.1g/cm3, hardness 3-5. Magnesite can be divided into two types: crystalline and amorphous according to its crystallization state. Crystalline magnesite is rhombohexahedral, columnar, plate-like, granular, dense, soil-like and fibrous, etc. It often contains calcium and manganese isomorphs. Fe2+

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

Hebei Messi Biology Co., Ltd. stated that hydromagnesite is a newly developed high-magnesium ore, which can be used as a flame-retardant filler. Hydromagnesite is a natural basic magnesium carbonate. The ore has high magnesium content, white quality and low impurity content. It is a high-quality magnesium-containing non-metallic mineral material and a high-quality raw material for
