Product Description

Ammonium dihydrogen phosphate, a chemical agent, also known as monoammonium phosphate, is a white crystal with the chemical formula of NH4H2PO4. It will decompose into ammonium metaphosphate (nh4po3) when heated. It can be made by the reaction of ammonia and phosphoric acid. It is mainly used as a fire retardant for fertilizer, wood, paper and fabric, as well as as pharmaceutical and ruminant feed additives.

[purpose]

It is used as a fire retardant for phosphate fertilizer, wood, paper and fabric (such as the extinguishing agent for match stems and candle wicks), as well as in the preparation of drugs. It is also used as feed additive for ruminants.

[performance]

Stable in air. When the temperature is higher than the melting point, ammonia and water are lost by decomposition to form ammonium metaphosphate and phosphoric acid mixture. There is a small part of decomposition at 100 ℃.

As fertilizer, ammonium phosphate is applied during crop growth. Ammonium phosphate is acidic in soil and may have adverse effects if it is too close to seeds. It is better than procalcium and ammonium sulfate in acidic soil and better than other fertilizers in alkaline soil; It should not be mixed with alkaline fertilizer to avoid reducing fertilizer efficiency. If lime is to be used in acid soil in the south, monoammonium phosphate should be applied after a few days.
