High-Purity Magnesium Hydroxide Raw Powder

    High-Purity Magnesium Hydroxide Raw Powder

    Produced from magnesium chloride via the brine-ammonia-lime combined process: MgCl₂ + 2NH₃·H₂O → Mg(OH)₂↓ + 2NH₄Cl. Features: high purity, good whiteness, low impurities, uniform particle distribution. MX-1/MX-2 benchmark against Martinswerk (Germany) and Kyowa (Japan), widely used in high-end low-smoke halogen-free cable materials.
