PHOSPHATES
Di Ammonium Phosphate
DAP is used as plant food, it temporarily increases the soil pH, but over a long term the treated ground becomes more acidic than before upon nitrification of the ammonium. It is incompatible with alkaline chemicals because its ammonium ion is more likely to convert to ammonia in a high-pH environment. The average pH in solution is 7.5–8. The typical formulation is 18-46-0 (18% N, 46% P2O5, 0% K2O).
DAP can be used as a fire retardant. It lowers the combustion temperature of the material, decreases maximum weight loss rates, and causes an increase in the production of residue or char. These are important effects in fighting wildfires as lowering the pyrolysis temperature and increasing the amount of char formed reduces that amount of available fuel and can lead to the formation of a firebreak. It is the largest component of some popular commercial firefighting products.
DAP is also used as a yeast nutrient in winemaking and brewing mead; as an additive in some brands of cigarettes purportedly as a nicotine enhancer; to prevent afterglow in matches, in purifying sugar; as a Flux for soldering tin, copper, zinc and brass; and to control precipitation of alkali-soluble and acid-insoluble colloidal dyes on wool.[1]

Di Calcium Phosphate
Dicalcium phosphate is mainly used as a dietary supplement in prepared breakfast cereals, dog treats, enriched flour, and noodle products. It is also used as a tableting agent in some pharmaceutical preparations, including some products meant to eliminate body odor. Dicalcium phosphate is also found in some dietary calcium supplements (e.g. Bonexcin). It is used in poultry feed. It is also used in some toothpastes as a tartar control agent.
Mono Ammonium Phosphate
Monoammonium phosphate used as fire-extinguishing agent for fabric,woods,paper,For food grade,ammonium phosphate monobasic is mainly used as ferment agent,nourishment,and so on,Used as a high eff ective non-0chloride N/Pcompound fertilizer in agriculture;monoammonium phosphate contains totally 73% fertilizer elements;May used as a basic raw materials for N、P、K compound fertilizer.
Mono Calcium Phosphate
Use in fertilisers Superphosphate fertilizers are produced by treatment of "phosphate rock" with acids. Using phosphoric acid, fluorapatiteis converted to Ca(H2PO4)2:
Use as leavening agent, Calcium dihydrogen phosphate is used in the food industry as a leavening agent, i.e., to cause baked goods to rise. Because it is acidic, when combined with an alkali ingredient, commonly sodium bicarbonate (baking soda) or potassium bicarbonate, it reacts to produce carbon dioxide and a salt. Outward pressure of the carbon dioxide gas causes the rising effect. When combined in a ready-made baking powder, the acid and alkali ingredients are included in the right proportions such that they will exactly neutralize each other and not significantly affect the overall pH of the product. ACMP and MCP are fast acting, releasing most carbon dioxide within minutes of mixing. It is popularly used in pancake mixes. In double acting baking powders, MCP is often combined with the slow acting acid sodium acid pyrophosphate(SAPP).

Mono Di Calcium Phosphate
Uses mainly as mineral in feed production.
Mono Kalium Phosphate
Fertilizer-grade MKP powder contains the equivalent of 52% P2O5 and 34% K2O, and is labeled 0-52-34. MKP powder is often used as a nutrient source in the greenhouse trade and in hydroponics. It is also use in as nutrient source for feed application in aquaculture.
Mono Sodium Phosphate
Monosodium phosphate is used as PH buffer, characteristic improving agent, emulsification agent, nutritional supplement, antioxidizer brine penetrable agent, sugar clarifier, stabilizer, coagulant, fowl depilatory agent.
Sodium Acid Pyrophosphate
Disodium pyrophosphate is a popular leavening agent found in baking powders. It combines with sodium bicarbonate to release carbon dioxide:
It is an acid source for reaction with baking soda to leaven baked goods. In baking soda, it is often labeled as food additive E450. In cured meats, it speeds the conversion of sodium nitrite to nitrite (NO2−) by forming the nitrous acid (HONO) intermediate, and can improve water-holding capacity. Disodium pyrophosphate is also found in browns and other potato products, where it is used to keep the color of the potatoes from darkening.
In leather treatment, it can be used to remove iron stains on hides during processing. It can stabilize hydrogen peroxidesolutions against reduction. It can be used with sulfamic acid in some dairy applications for cleaning, especially to remove soapstone. When added to scalding water, it facilitates removal of hair and scurf in hog slaughter and feathers and scurf in poultry slaughter. In petroleum production, it can be used as a dispersant in oil well drilling muds.

Sodium Tri Poly Phosphate
The majority of STPP is consumed as a component of commercial detergents. It serves as a "builder," industrial jargon for a water softener. In hard water, detergents are deactivated. Being a highly charged chelating agent, TPP5- binds to dications tightly and prevents them from interfering with the sulfonate detergent.
Food applications STPP is a preservative for seafood, meats, poultry, and animal feeds. It is common in food production as E number E451. In foods, STPP is used as an emulsifier and to retain moisture. Many governments regulate the quantities allowed in foods, as it can substantially increase the sale weight of seafood in particular. The United States Food and Drug Administration lists STPP as "generally recognized as safe.".
Other uses (hundreds of thousands of tons/year) include "ceramics (increase viscosity of the glazes upto a certain limit), leather tanning (as masking agent and synthetic tanning agent - SYNTAN), anticaking, setting retarders, flame retardants, paper, anticorrosion pigments, textiles, rubber manufacture, fermentation,antifreeze. TPP is used as a polyanion crosslinker in polysaccharide based drug delivery.

Sodium Hexa Meta Phosphate
SHMP is used as a sequestrant and has applications within a wide variety of industries, including as a food additive in which it is used under the E number E452i. Sodium carbonate is sometimes added to SHMP to raise the pH to 8.0-8.6, which produces a number of SHMP products used for water softening and detergents. Also used as a dispersing agent to break down clay and other soil types.
One of the lesser-known uses for sodium hexametaphosphate is as a deflocculant in the making of terra sigillata, a ceramic technique using a fine particled slip. The sodium hexametaphosphate or another deflocculant allows the clay particles of an ordinary slip to remain suspended for an extended period of time; after 24hrs or more, the slip separates into layers with the larger particles at the bottom, and the finest particles can be siphoned off and applied to a green ware ceramic surface. It is also used as a deflocculant or dispersant for the ASTM D422 - 63(2007) Standard Test Method for Particle-Size Analysis of Soils.
Sodium hexmetaphosphate in foods,Artificial maple syrup, canned milk, cheese powders and dips, imitation cheese, whipped topping, packaged egg whites, roast beef, fish fillets, fruit jelly, frozen desserts, salad dressing, herring, breakfast cereal, ice cream, beer, and bottled beverages, among other foods, can contain sodium hexametaphosphate.

Tri Sodium Phosphate
Trisodium phosphate was at one time extensively used in formulations for a variety of consumer grade soaps and detergents, and the most common use for trisodium phosphate has been in cleaning agents. The pH of a 1% solution is 12 and the solution is sufficiently alkaline to saponify grease and oils. In combination with surfactants, TSP is an excellent agent for cleaning everything from laundry to concrete driveways. This versatility and low manufacturing price made TSP the basis for a plethora of cleaning products sold in the mid-20th century. TSP is still sold and used as a cleaning agent but since the late 1960s its use has diminished in the United States and many other parts of the world because like many phosphate-based cleaners it is known to cause extensive eutrophication of lakes and rivers once it enters a water system.
TSP is commonly used after cleaning a surface with mineral spirits in order to remove hydrocarbon residues and may be used with household chlorine bleach in the same solution without hazardous reactions. This mixture is particularly effective for removing mildew, but is less effective at removing mold.
Although it is still the active ingredient in some toilet bowl cleaning tablets, TSP is generally not recommended for cleaning bathrooms because it can stain metal fixtures and can damage grout.
Chlorinated trisodium phosphate With the formula Na3PO4.¼ NaOCl.11 H2O, the material called chlorinated trisodium phosphate is used as a disinfectant and bleach, like sodium hypochlorite. It is prepared using NaOCl in place of some of the base to neutralize phosphoric acid.
Trisodium phosphate is an approved flux for use in hard soldering joints in medical grade copper plumbing. The flux is applied as a concentrated water solution and dissolves copper oxides at the temperature used in copper brazing. Residues are water soluble and can be rinsed out before plumbing is put into service.TSP is used as an ingredient in fluxes designed to deoxygenate nonferrous metals for casting. It can be used in ceramic production to lower the flow point of glazes.
TSP is still in common use for the cleaning, degreasing and deglossing of walls prior to painting. TSP breaks the gloss of oil based paints and opens the pores of latex based paint providing a surface better suited for the adhesion of the subsequent layer.
Sodium phosphates (monosodium phosphate, disodium phosphate, and trisodium phosphate) are approved as a food additive in the EU; used as antioxidant agent.
Exercise performance enhancement, Trisodium phosphate has gained a following as a nutritional supplement that can improve certain parameters of exercise performance. The basis of this belief is the fact that phosphate is required for the energy-producing Krebs cycle central to aerobic metabolism. Phosphates are available from a number of other sources that are much milder than TSP. While TSP is not toxic per se, it is severely irritating to gastric mucosa unless used as part of a buffered solution.
