Magnesium hydroxide [Mg(OH)₂] is an inorganic ceramic compound commonly produced as a fine white powder, widely used as a flame retardant additive in polymers, rubbers, and composite materials. It is employed in construction materials (fireproofing, fire-rated coatings), wastewater treatment (pH adjustment, heavy metal precipitation), and pharmaceutical applications (antacid formulations). Compared to halogenated flame retardants, Mg(OH)₂ is valued for producing minimal smoke and toxic gases when decomposed at elevated temperatures, making it the preferred choice in safety-critical applications where low-toxicity combustion products are essential.
