Hebei Messi Biology Co., Ltd. stated that hydromagnesite is a newly developed high-magnesium ore that can be used as a flame retardant filler. Hydromagnesite is a natural basic magnesium carbonate. The ore has a 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 manufacturing magnesium materials. It has a wide range of uses. Hydromagnesite loses all its crystal water at 340°C, and magnesium hydroxide begins to decompose structural water. At 477°C, all structural water is removed, and magnesium carbonate begins to decompose. When the temperature rises to 727°C, magnesium carbonate completely decomposes to obtain magnesium oxide. Such decomposition conditions have a certain correspondence with the combustion of polymer materials, so hydromagnesite can be used as a flame retardant for polymer materials.
