Aluminum hydroxide
Aluminum Hydroxide, chemically known as Al(OH)₃, is a white, odorless, and odorless powder or gelatinous substance. It is widely used in pharmaceuticals as an antacid to neutralize stomach acid and relieve indigestion and heartburn. Beyond healthcare, aluminum hydroxide is a crucial component in water purification, fire retardants, and as a precursor or filler in various industrial applications. It functions as a flame retardant by releasing water upon heating, thus cooling the material and diluting flammable gases. Due to its amphoteric nature, it can react both as an acid and base, enhancing its versatility. Aluminum hydroxide is often utilized in manufacturing aluminum salts and in producing aluminum oxide.
