Phosphate Posted on 2008-08-26 [India]
Products Detail :- Phosphates are the naturally occurring form of the element phosphorus, found in many phosphate minerals. Elemental phosphorus and phosphides are not found (rare phosphide minerals may be found in meteorites). In mineralogy and geology, phosphate refers to a rock or ore containing phosphate ions.
Di Ammonium Phosphate
Diammonium phosphate (DAP) (chemical formula (NH4)2HPO4 ) is one of a series of water-soluble ammonium phosphate salts which can be produced when ammonia reacts with phosphoric acid. DAP is used as a fertilizer and a fire retardant. When applied as plant food, it temporarily increases the soil pH (more basic), 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.
Mono Ammonium Phosphate
Ammonium phosphate : Molar Mass = 149.12g/mol. The normal ammonium phosphate, (NH4)3PO4, 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 (NH4)2HPO4. It is soluble in water, and the aqueous solution on boiling loses ammonia and the acid phosphate NH4H2PO4 is formed. Ammonium phosphate is used as an ingredient in some fertilizers as a high source of elemental nitrogen.
Diammonium Hydrogen Phosphate : or diammonium phosphate, (NH4)2HPO4, is formed by evaporating a solution of phosphoric acid with excess of ammonia. It crystallizes in large transparent prisms, which melt on heating and decompose, leaving a residue of metaphosphoric acid, (HPO3).
Ammonium dihydrogen phosphate, or monoammonium phosphate, NH4â?¢H2PO4, is formed when a solution of phosphoric acid is added to ammonia until the solution is distinctly acid. It crystallizes in quadratic prisms. Monoammonium phosphate is often used in the blending of dry agricultural fertilizers. It supplies soil with the elements nitrogen and phosphorus in a form which is usable by plants. The compound is also a component of the ABC powder in some dry chemical fire extinguishers.
Tri Sodium Phosphate
Trisodium phosphate (TSP), available at most hardware stores in white powder form, is a cleaning agent, stain remover and degreaser, commonly used to prepare surfaces for painting. It can also be called trisodium orthophosphate and has the chemical formula Na3PO4; however, it is generally found in hydrated forms. It is a highly water-soluble ionic salt. Solutions of it dissolved in water have an alkaline pH.
It can also be found as a food additive; it is used as an acidity regulator (buffering agent), emulsifier, thickening agent, nutrition enlargement agent and sequestrant (metal-chelating agent). In these uses, all sodium phosphates may be collectively referred to as sodium phosphate, or by E number E339. The same is true when sold as an enema, working as a laxative to treat constipation. Sodium phosphate enemas are sold over-the-counter in the United States. However, it should not be confused with the related compounds sodium dihydrogen phosphate, also known as monosodium phosphate or MSP, and disodium phosphate.
Mono Potassium Phosphate
Monopotassium phosphate (also potassium dihydrogen phosphate, KDP, or monobasic potassium phosphate, MKP) -- KH2PO4 is a soluble salt which is used as a fertilizer, a food additive and a fungicide. It is a source of phosphorus and potassium, and is a buffering agent. When used in fertilizer mixtures with urea and ammonium phosphates, it minimizes escape of ammonia by keeping the pH at a relatively low level.
Fertilizer grade MKP contains 52% P2O5 and 34% K2O, and is labeled 0-52-34. It is often used as a nutrient source in the greenhouse trade and in hydroponics. It is one of the components of Gatorade and is used as an additive in cigarettes. At 400°C it decomposes, by loss of water, to potassium metaphosphate (KPO3)
