Introduction to Magnesium Hydroxide
Magnesium hydroxide, with the chemical formula Mg(OH)₂, is an inorganic compound widely used in various industries. It is a white powder that is slightly soluble in water. In the environmental protection field, it serves as an excellent neutralizer for acidic wastewater due to its high buffering capacity and low solubility, which helps to adjust the pH value without causing excessive alkalinity. In the field of flame – retardant materials, magnesium hydroxide can decompose endothermically when heated, absorbing a large amount of heat and releasing water vapor, thus effectively suppressing the spread of fire and reducing the generation of toxic gases. Additionally, it is also used in the pharmaceutical industry as an antacid to relieve symptoms such as heartburn and indigestion. Magnesium Hydroxide
