Widely used as a flame retardant in plastics, coatings, and construction materials due to its ability to release water vapor when heated, which helps suppress fire and reduce smoke. Commonly formulated into polymer-based products such as cables, conveyor belts, and insulation to improve fire safety. Also used as an antacid in pharmaceuticals to neutralize stomach acid and relieve indigestion or heartburn. Employed in wastewater treatment to neutralize acidic effluents and remove heavy metals by precipitation. Added to flue gas treatment systems to reduce sulfur dioxide emissions in industrial air pollution control. Its low toxicity and environmental compatibility make it suitable for applications in food processing, cosmetics, and personal care products.
