Ammonium phosphate dibasic is widely used as a fertilizer in agriculture due to its high phosphorus and nitrogen content, which are essential nutrients for plant growth. It helps in promoting root development, improving crop yield, and enhancing overall plant health. In the food industry, it serves as a leavening agent in baked goods, helping dough rise by producing carbon dioxide gas when heated. Additionally, it is utilized as a flame retardant in various materials, including textiles and wood, by releasing ammonia and forming a protective char layer that inhibits combustion. In water treatment, it acts as a nutrient source for microorganisms in biological wastewater treatment processes, aiding in the breakdown of organic pollutants. It is also employed in the production of ceramics and as a buffering agent in laboratory settings to maintain stable pH levels.
