Commercial Dicalcium Phosphate is not a chemicallydefined entity, but is a mixture of varying amounts of dicalcium and monocalcium phosphates, Phosphoric Acid, calcium carbonate, and impurities, depending on the origin of the raw material and procedures employed in its industrial production.
Phosphoric Acid: In the past, phosphoric acid was shipped to granulation plants that flourished in farming areas. There it was mixed with ammonia to make phosphate fertilizer. There it was mixed with ammonia to make phosphate fertilizer.
Dicalcium Phosphate is a calcium salt of phosphoric acid. It is produced by reacting wet process defuorinated phosphoric acid with calcium carbonate. Excellent source of phosphorus and calcium.
Calstar® Dicalcium Phosphate, Dihydrate Granular is a white granular USP grade of Dicalcium Phosphate Dihydrate used as a calcium and/or phosphorus nutrient supplement in pharmaceuticals and multivitamins. Calstar® can be used as an excipient in the preparation of tablets by direct compression or wet granulation.
The rock phosphate is first digested with sulphuric acid, yielding phosphoric acid. After further filtration, purification and defluorination steps, this "feed grade" phosphoric acid is reacted with a calcium source such as quicklime and/or limestone under strictly controlled conditions. Thus, anhydrous dicalcium phosphate (CaHPO4) is formed.
Global Dicalcium Phosphate Market Research Report By Production Method (Phosphoric Acid Route, And Hydrochloric Acid Route), Application (Animal Feed, Fertilizer, Food Beverage, Pharmaceuticals, Cosmetics, And Others) And By Region Forecast Till 2023
(Cl. 23109) The present invention is concerned with a process for the manufacture of dicalcium phosphate dihydrate from a calcium compound, phosphoric acid and/ or a phosphoric acid salt and optionally a basic compound in the presence of Water.
Phosphogypsum is the principal byproduct produced by the wet processes involved in the manufacture of phosphoric acid, and generally contains an amount of fluoride that needs to be fixed or removed.
Feb 06, 2001· A method of producing dicalcium phosphate from calcium phosphate includes reacting the calcium phosphate with a mineral acid such as sulphuric acid to produce a calcium salt and phosphoric acid. The calcium salt may then be hydrolyzed to form a calcium alkali which may then be reacted with the phosphoric acid to produce dicalcium phosphate.
Phosphoric acid technical grade can be used to produce variety of phosphate,refractory clay and rust –proof coating； phosphatingprocess and polish for metal surface,also can be used as a catalyst, inorganic binder, desiccant, cleaning agent. PHOSPHORIC ACID PACKING 【Packing】： In 20L,200L plastic drum or 1000L IBC tank.

Phosphoric Acid is manufactured from Rock Phosphate. Phosphate rock is fed to a series of reactors along with recycled phosphoric acid from the process. The phosphoric acidfluoroapatite slurry is mixed with sulphuric acid which is added to the reactor series as a leaching agent.
Dicalcium phosphate dihydrate (DCPD) is a leavening acid and source of calcium enrichment. It has a neutralizing value of 33 and is very slow reacting. Origin. DCPD is synthetically produced from calcium carbonate and phosphoric acid.
Jointstock company "Lifosa" is Lithuanian phosphate industry company, situated in Kėdainiai, the geographical center of Lithuania. AB "Lifosa" is one of the biggest producers of fertilizers in the Eastern Europe, exporting more than 98% of its production.
Full Text: This invention relates to a process for the manufacture of feed grade dicalcium phosphate. Dicalcium phosphate known, as DCP is a commonly used animal feed supplement and it is desirable to obtain dicalcium phosphate free of contaminants, particularly fluoride containing compounds.
A new process for production of purified phosphoric acid ... A new process for production of purified phosphoric acid and/or fertilizergrade dicalcium phosphate has been developed and tested with various grades of phosphatic materials as the source of P 2O 5.
