Details:

Product Name:	Monoammonium Phosphate
Molecular Formula:	NH4H2PO4
CAS NO.:	7722-76-1
Place of Origin:	China

Chemical properties

Monoammonium phosphate is soluble in water and crystallizes from it as the anhydrous salt in the tetragonal system, as elongated prisms or needles. It is practically insoluble in ethanol.

Solid monoammonium phosphate can be considered stable in practice for temperatures up to 200 °C, when it decomposes into gaseous ammonia NH3 and molten phosphoric acid H3PO4. At 125 °C the partial pressure of ammonia is 0.05 mm Hg. A solution of stoichometric monoammonium phosphate is acidic (PH 4.7 at 0.1% concentration, 4.2 at 5%).

Application:

Ø Agriculture

The largest use of monoammonium phosphate by weight is in agriculture, as an ingredient of fertilizers. It supplies soil with the elements nitrogen and phosphorous in a form usable by plants. Its NPK label is 12-61-0 (12-27-0), meaning that it contains 12% by weight of elemental nitrogen and (nominally) 61% of phosphorous pentoxide P2O5, or 27% of elemental phosphorus.

Ø Fire extinguishers

The compound is also a component of the ABC powder in some dry chemical fire extinguishers.

Ø Optics

Monoammonium phosphate is a widely used crystal in the field of optics due to its birefringence properties. As a result of its tetragonal crystal structure, this material has negative uniaxial optical symmetry with typical refractive indices no = 1.522 and ne = 1.478 at optical wavelengths.

Ø Electronics

Monoammonium phospate crystals are piezoelectric, a property required in some active sonor transducers (the alternative being transducers that use magnetostriction). In the 1950s ADP crystals largely replaced the quartz and Rochelle salt crystals in transducers because they are easier to work than Quartz and, unlike Rochelle Salt, are not deliquescent.

Ø Toys

Being relatively non-toxic, MAP is also a popular substance for recreational crystal growing, being sold as toy kits mixed with dyes of various colors.
