Magnesium hydroxide: an excellent choice in multiple fields
Magnesium hydroxide, with the chemical formula Mg (OH) ₂, plays an indispensable role in industry and daily life. From the appearance, it appears as a white and delicate powder with a uniform texture, giving people a sense of purity.
In terms of physical properties, magnesium hydroxide has a high decomposition temperature, usually between 340-490 ℃. This characteristic enables it to maintain relative stability in high-temperature environments, providing a solid foundation for its use in numerous high-temperature related application scenarios. At the same time, it also has a lower packing density, which is not only beneficial for product storage and transportation, but also demonstrates unique advantages in some applications that require material density, such as plastic filling, without increasing the weight of the product too much.
In terms of chemical properties, magnesium hydroxide is a weak base with a certain alkaline buffering capacity. It can undergo neutralization reaction with acid to generate magnesium salts and water, which makes it highly effective in the field of wastewater treatment. It can effectively neutralize acidic wastewater, adjust the pH value of wastewater, and meet environmental discharge standards. Moreover, in some specific chemical reactions, magnesium hydroxide can also serve as a catalyst or catalyst carrier, participating in and promoting the progress of the reaction, exhibiting good chemical activity and selectivity.
