Monoammonium phosphate or Ammonium dihydrogen phosphate or Mono Ammonium Phosphate, NH4•H2PO4, is formed when a solution of phosphoric acid is added to ammonia until the solution is distinctly acid. It crystallizes in quadratic prisms. It is often used in the blending of dry agricultural fertilizers. It supplies soil with the elements nitrogen and phosphorus in a form which is usable by plants. The compound is also a component of the ABC powder in some dry chemical fire extinguishers. This substance is also supplied in a jade green or aquamarine crystal growing box kit for kids.
Uses:
Monoammonium phosphate (MAP) or Mono ammonium phosphate is used as a fire-prevention agent for fabric, timber and paper, as well as a fire-prevention coating, and dry powder for fire extinguisher. For food grade MAP is mainly used as a fermentation agent, nourishment, and so on. It is used as a high effective non-chloride N, P compound fertilizer in agriculture. Its total nourishment (N=P2O5) is at 73%, and may be used as a basic raw material for N, P and K compound fertilizer.
