Magnesium hydroxide (Mg(OH)₂) is an inorganic compound widely recognized for its applications across environmental, chemical, pharmaceutical, and industrial sectors. Appearing as a white, crystalline, or fine amorphous powder, it is known for its basic (alkaline) nature and moderate reactivity. In its naturally occurring form, it is found as the mineral brucite, though industrial production typically involves precipitation reactions between magnesium salts (like magnesium chloride) and alkaline substances (like sodium hydroxide). Magnesium hydroxide acts primarily as an antacid, flame retardant, pH regulator, and neutralizing agent, making it a versatile compound with broad commercial significance.
From a market definition standpoint, magnesium hydroxide is often categorized according to its application-specific grade—industrial, pharmaceutical, or environmental. The industrial-grade magnesium hydroxide is used extensively in wastewater treatment, flue gas desulfurization (FGD), flame retardants, and in the production of magnesium-based chemicals. It plays a critical role in neutralizing acidic wastewater, precipitating heavy metals, and maintaining regulatory compliance for discharge standards. In environmental protection, magnesium hydroxide is gaining traction as a greener alternative to traditional neutralizing agents such as caustic soda (NaOH) or lime (Ca(OH)₂), thanks to its lower exothermicity, ease of handling, and lower corrosiveness. Additionally, its use as a non-halogenated flame retardant in polymer composites—particularly in wire and cable insulation, construction materials, and automotive parts—is expanding due to increasing safety regulations and the drive toward halogen-free systems.
Market growth for magnesium hydroxide is being shaped by several macroeconomic and regulatory trends. Environmental regulations are among the strongest drivers, particularly in developed regions such as North America, Europe, and parts of East Asia, where there is mounting pressure on industries to treat effluents effectively and reduce harmful emissions. In this context, magnesium hydroxide offers a safe and cost-effective solution for pH control, heavy metal precipitation, and odor control in municipal and industrial wastewater treatment. It also plays an increasingly important role in air pollution control systems, especially in flue gas desulfurization processes for coal-fired power plants and waste incinerators, where it reacts with sulfur dioxide to form magnesium sulfite or sulfate.
Another major driver is the rising demand for flame retardants in construction, electronics, and transportation. As fire safety standards tighten and halogenated flame retardants face regulatory restrictions due to environmental and health concerns, magnesium hydroxide and similar inorganic alternatives (like aluminum hydroxide) are becoming preferred solutions. Magnesium hydroxide is particularly valued because it decomposes endothermically at high temperatures, releasing water vapor that cools surfaces and dilutes flammable gases, while leaving non-toxic residues. This performance, combined with its low smoke and toxicity profile, makes it ideal for sustainable flame-retardant applications.
