With small particle size, large specific surface area, and high activity, it’s widely used in lithium battery cathodes (LiMn₂O₄, LiCoO₂, LiFePO₄, ternary materials). A new inorganic smoke-suppressant flame retardant, it has good thermal stability, is non-volatile, and non-corrosive to equipment. It has a nano-layered structure (decomposes to MgO at 350℃, insoluble in water), high purity, and can be in-situ coated. It disperses well in PA/PP/ABS/PVC, enhancing flame retardancy, smoke suppression, and anti-dripping for rubbers, cables, and home appliances.
