Magnesium hydroxide plays a crucial role in industrial applications. Firstly, it is widely used as a flame retardant in industries such as plastics, rubber, and cables, effectively suppressing combustion and reducing smoke production, thereby providing strong security for the safety performance of products. Secondly, magnesium hydroxide has significant advantages in the field of environmental protection, as it can neutralize acidic wastewater, reduce the corrosiveness of wastewater, and minimize environmental pollution. Moreover, magnesium hydroxide can also serve as a catalyst carrier, enhancing the activity and stability of catalysts in chemical reactions.

In the field of flame retardants, magnesium hydroxide boasts high thermal stability, absorbing a significant amount of heat during decomposition, which can significantly reduce combustion temperatures. Moreover, its decomposition products are magnesium oxide and steam, which can dilute the concentration of flammable gases and oxygen, thereby preventing the combustion process.

In the field of environmental protection, magnesium hydroxide effectively neutralizes hydrogen ions in acidic wastewater, lowering the pH of the effluent and reducing environmental harm. Additionally, it reacts with heavy metal ions in the wastewater to form precipitates, removing the heavy metals and further purifying the water quality.

Magnesium hydroxide, as a catalyst carrier, boasts a high specific surface area and excellent chemical stability, providing an ideal attachment environment for catalysts and enhancing their dispersibility and activity. Additionally, magnesium hydroxide itself possesses certain catalytic properties, enabling it to synergize with catalysts to further promote the progression of chemical reactions.
