		Ammonium nitrate, NH, is prepared by neutralizing nitric acid with ammonia, or ammonium carbonate, or by double decomposition between potassium nitrate and ammonium sulfate.
		Ammonium nitrite, NH, is formed by oxidizing ammonia with ozone or hydrogen peroxide ; by precipitating barium or lead nitrites with ammonium sulfate, or silver nitrite with ammonium chloride.
		The normal phosphate, (NH,is obtained as a crystalline powder, on mixing concentrated solutions of ammonia and phosphoric acid, or on the addition of excess of ammonia to the acid phosphate (NH It is soluble in water, and the aqueous solution on boiling loses ammonia and the acid phosphate NH is formed.

	Patent 4239542: Water-soluble flame retarder and process for preparing the same
		Therefore, since the reaction efficiency is lowered due to large excess of water, the degree of condensation of the obtained condensed ammonium phosphate is not uniform and a portion of the condensed ammonium phosphate having a degree of condensation of less than 20 and the unreacted urea are increased.
		In order to produce the high condensed ammonium phosphate having an average degree of condensation of 20 to 60 and simultaneously to by-produce the urea compounds in particular proportions, urea is employed in an amount of 2 to 4 moles per mole of phosphoric acid.
		Therefore, a low condensed ammonium phosphate, especially a water-soluble low condensed ammonium phosphate having a degree of condensation of 1 to 4 is preferably employed as a starting material, because a completely water-soluble flame retarder cannot be obtained when a high condensed ammonium phosphate is employed as a starting material.

	Phosphate fertiliser
		High analysis phosphates are also now imported (especially ammonium phosphates with a high concentration of nitrogen and phosphorus) and often blended with locally produced single strength superphosphate to provide a double strength fertiliser.
		Phosphate is produced by the Phosphate Island Company that in 1998 produced 587 000 tonnes of phosphate rock valued at A$45million (A$3.4 million after tax).

		Since calcium phosphate is only slightly soluble in water, it is not very suitable as a source of the phosphorus necessary for plant life; however, by treating it with sulfuric acid the soluble calcium acid phosphate known as superphosphate of lime is formed.
		Other important inorganic phosphates include ammonium phosphate, important as a fertilizer; trisodium phosphate, used in detergents and for softening water; and disodium phosphate, used to some extent in medicine and in preparing baking powders.
		Nucleotides are phosphate esters that play an important role in the conservation and use of the energy released in the metabolism of foods in the body; adenosine triphosphate is an important nucleotide.

	Ammonia (Site not responding. Last check: 2007-11-06)
		Ammonia is found in small quantities as the carbonate in the atmosphere, being produced from the putrefaction of nitrogenous animal and vegetable matter.
		Ammonium salts are also found in small quantities in rain-water, whilst ammonium chloride (sal-ammoniac) and ammonium sulfate are found in volcanic districts; and crystals of ammonium bicarbonate have been found in Patagonian guano.
		The aqueous solution of ammonia is very basic, and since it is a weak electrolyte, the solution will contain a small amount of ammonium hydroxide (NH It does not support combustion, and it does not burn readily unless mixed with oxygen, when it burns with a pale yellowish-green flame.

		Typically, the glyphosate component is added as glyphosate acid, an ammonium salt of glyphosate acid (e.g., a mono-ammonium salt of glyphosate acid) or a mixture thereof and is accompanied by small quantities of impurities typically found in and produced during the manufacture of such materials.
		In this manner, the ammonium glyphosate may be preferentially driven towards the mono-ammonium salt and the oxalic acid be partially or completely neutralized to form the mono-ammonium oxalate salt, di-ammonium oxalate salt or mixtures thereof to produce a mixture of the glyphosate salt and oxalate salt having the desired pH.
		C., a solution of ammonium hydroxide (29% by weight ammonia) is then fed to the blender and sprayed by nozzles onto the mixture of acids to form a reaction mass.

		Ammonium-based compounds Ammonium phosphates are believed to act as fire retardants by their ability to increase markedly the conversion of organic matter to char during burning and thus to decrease the formation of flammable carbon containing gases.
		Ammonium sulfate decomposes in the temperature range of 400 to 5000F (204 to 2600C) with an associated odor of released ammonia.
		Under the effect of moisture, ammonium sulfate will migrate due to the periodic solubilization upon moisture condensation followed by re-crystallization upon subsequent moisture evaporation so that the solubilized compounds are removed from portions of the cellulose.

		Phosphates are natural nutrients necessary for plant growth and health, and are the most stable compounds to deliver phosphorus to plant roots.
		Phosphates offer a trio of benefits: the application of phosphates prepares the water or cleaning environment then traps and holds the dirt or oils so that it can be rinsed away.
		Phosphates are available to animals and humans when plants (and other animals) are consumed and are then returned to the environment through animal and human waste and decomposition of plants and animals.

	Abstract of CEH report Ammonium Phosphates (Site not responding. Last check: 2007-11-06)
		The world ammonium phosphate industry has been depressed since the early 1980s as a result of a major increase in world capacity beginning in the late 1970s, combined with a significant slowdown in the rate of growth of phosphate fertilizer consumption, its major end-use market.
		World phosphate fertilizer consumption is not likely to exceed the 1989 peak until about or beyond the end of the forecast period in 2007.
		The fob value of the world ammonium phosphate industry in 2002 is roughly estimated at $3.5 billion.

		In order to prevent the misuse of ammonium nitrate in improvised explosives, it is necessary physically separate the fuel from the ammonium nitrate and also prevent the penetration of the liquid fuel into the fertilizer particles.
		For example, ammonium phosphate may be used in combination with a polymer, and especially with those polymers disclosed herein.
		Ammonium nitrate is the most preferred fertilizer particle for use with the invention because, when combined with a fuel source such as hydrocarbon materials, it acts as a powerful oxidizer.

	Commercial Nitrogen Fertilizers
		Pure ammonium nitrate is very hygroscopic and can be explosive under certain conditions; however, present fertilizer grades of the material are specially conditioned, and when stored and handled properly, pose no problem or hazard.
		Ammonium phosphates are manufactured in a wide variety of forms and formulations including mono-ammonium phosphate (MAP), diammonium phosphate (DAP) and several ammonium polyphosphates.
		Inorganic compounds, such as magnesium ammonium phosphate, and organic compounds, such as urea-formaldehyde (ureaform) and isobutylidene diurea (IBDU), are often used to supply nitrogen at slow but fairly predictable rates.

	Agronomic Comparisons of Fluid and Dry Fertilizers (Site not responding. Last check: 2007-11-06)
		For instance, it would not be valid to compare a highly water-soluble phosphate in fluids with a solid phosphate of low water solubility.
		However, when solids such as diammonium phosphate (DAP), monoammonium phosphate, or ammonium polyphosphate were compared with fluids such as 10-34-0, 8-24-0, or 11-37-0 under similar conditions, long-term studies have shown these to be essentially equal in nutritive value.

		Ammonium fertilizers are superior as compared to nitrate fertilizers in very slightly alkaline soils (pH 7-7.5) due to its side effect as a soil acidifier.
		Ammonium carbonate is produced upon urea hydrolysis, which dissociates to form NH and CO In alkaline conditions, NH forms NH that may be lost by volatilization (Finck, 1982; Mortvedt et al., 1999).
