Ammonium phosphate dibasic is widely used as a fertilizer in agriculture due to its high nitrogen and phosphorus content, which are essential nutrients for plant growth. It helps improve soil fertility and promotes healthy crop development. In the food industry, it serves as a leavening agent in baked goods, helping dough rise and achieve a light texture. Additionally, it is utilized in fire extinguishers as a flame retardant, particularly for Class A fires, by releasing ammonia and forming a protective layer to suppress flames. In water treatment, it acts as a corrosion inhibitor, preventing scale formation and protecting metal surfaces in piping systems. Its versatility makes it valuable across various industries.
