Description

Ammonium Phosphate, Hemibasic is an inorganic salt with the chemical formula (NH4)2HPO4·(NH4)H2PO4. This compound serves as a crucial source of both nitrogen and phosphorus, making it a versatile intermediate and additive in various industrial and agricultural processes. It is primarily utilized in sectors requiring controlled nutrient release, flame retardancy, and as a buffering agent. Key industries that rely on this material include agriculture, specialty chemicals, and materials science.

Application

• Flame Retardant Formulations: Acts as an effective intumescent agent in plastics, textiles, and coatings, promoting char formation and reducing flammability.
• Specialty Fertilizers & Nutrient Solutions: Used in controlled-release fertilizers and high-purity hydroponic nutrient solutions due to its balanced N-P content.
• Chemical Synthesis Intermediate: Serves as a precursor in the production of other ammonium phosphates and specialty phosphate salts.
• Buffering Agent: Employed in laboratory and industrial processes where a stable phosphate buffer is required.
• Corrosion Inhibitor: Used in water treatment and anti-corrosion formulations for metal surfaces.
• Yeast & Fermentation Nutrient: Functions as a nitrogen and phosphorus source in microbial culture media and fermentation processes.
