1. Agrochemicals

• Provides Nitrogen and Phosphorus: Ammonium phosphate, in both granular and powdered forms, delivers nitrogen (N) and phosphorus (P), two vital macronutrients for plant development.
• Readily Available Phosphorus: It's a good source of readily available phosphorus, making it useful for addressing phosphorus deficiencies in the soil.

2. Performance Chemicals

• Synthesis of Other Phosphates: Ammonium phosphates can be transformed into other phosphate compounds through various chemical reactions.
• Inorganic Phosphate: Ammonium phosphate is used as an inorganic phosphate, which is added during processing in the form of biochemical compounds, such as preservatives and salts.

3. Construction

• Fire retardant: Ammonium phosphate is a widely used fire retardant. It works by releasing ammonia and phosphoric acid when heated, which then promote char formation and inhibit the release of flammable gases, thus slowing or preventing combustion.
• Flame Retardant: Ammonium phosphates are used to treat materials like wood, plywood, chipboard, and fiberboard to make them fire-resistant.
• Corundum Ceramics: Ammonium phosphate, specifically acid ammonium phosphates, can effectively bind corundum (aluminum oxide) particles, making it suitable for industrial applications like furnace linings.
• Binder in Dental Applications: Monoammonium phosphate is used as a binder in dental casting, specifically in precision investment casting compounds, to hold together particles of the investment material that forms the mold for teeth.
