  • Monoammonium phosphate (11-48-0) is a dry material being used for bulk blending or direct applications. Monoammonium phosphate has a
    lower ammonia content and may be less injurious to germinating seeds than diammonium phosphate. The general agronomic effects of diammonium and monoammonium phosphates are equal for most soils.
  • Ammonium dihydrogen phosphate (ADP), or monoammonium phosphate, NH4H2PO4, is formed when a solution of phosphoric acid is added to ammonia until the solution is distinctly acidic.
  • ADP is a widely used crystal in the field of optics due to its birefringence properties. ADP crystals are piezoelectric which is a property required in some active sonar transducers.
  • Monoammonium phosphate is made by neutralization of extraction phosphoric acid by ammonia, and drying of ready-made pulp of monoammonium phosphate in the DGD vehicles (drum granulator-dryer).
  • Boron is an essential micronutrient for all vascular plants. Boron deficiency causes rapid biochemical, physiological and anatomical aberrations. Ammonium phosphates with a variable boron content ranging from 0.1 to 1 % (w/w) were prepared by neutralizing phosphoric acid with ammonia and introducing sodium borate pentahydrate in variable amounts into the reaction mixture.
  • Mono ammonium dihydrogen phosphate and potassium dihydrogen phosphate (KDP) are also excellent chemicals for growing crystals. These chemicals work well by either supersaturation or saturation techniques.Mono ammonium phosphate produces crystals in the Tetragonal system of crystal symmetry. The most common crystal form is a four-sided, long column capped at each end by four-sided pyramids.
  • There are are two main dry powders used in fire fighting. Regular dry chemical for classes B or C fire, the major constituent being sodium bicarbonate (NaHCO3), and multi purpose dry chemical for A,B and C class fires, the major constituent being mono-ammonium phosphate (NH4H2PO4).
  • Magnesium phosphate cement materials are formed by reacting magnesium oxide with water-soluble phosphates such as monoammonium dihydrogen phosphate (ADP), which solidifies at ambient temperature through the formation of hydrated phases in the material.
  • Specialty Phosphates offers a variety of properties to the textile industry that are important at various stages of production. Monosodium phosphate, promote complete reduction and exhaustion of dye to minimize waste.
  • MAP production amounts to about 13m. tonnes a year, of which about 7-8m. tonnes are traded internationally. It is produced in around 10 countries. The largest producers are US, Chinese and Russian companies, who have large domestic markets to serve. The main exporters are producers in the US, Russia, and Morocco and the main import market is Brazil.
  • MAP is also produced by combining phosphoric acid and ammonia. The most common grade for MAP is 11% nitrogen and 52% phosphorus pentoxide. MAP is widely produced in granular form for direct application as a fertilizer or in bulk blending of dry fertilizers. The compound is also a component of some dry powder fire extinguishers. It is stored and transported as a solid at ambient temperatures.
