26 rows· PROCESS OF MAKING DICALCIUM PHOSPHATE. No Drawing. To all whom it may concern 7 Be it known that I, WALTER GLAESER, a subject of the GermanEmperor, and a resident,of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Processes of Making Dicalcium Phosphate, (Case A,) of which the following is a ...

It consumes not only forty percent more reagent acid than the superphosphate method of producing available phosphate, but also requires calcium hydroxide equivalent to the dicalcium phosphate produced. In my process, the use of milkoflime is eliminated and the acid consumed the production of dicalcium phosphate is reduced to about sixty ...

A process for producing phosphoric acid which comprises reacting aqueous sulfuric acid having from 50% to by weight sulfuric acid with a recycled dicalcium phosphate material and with phosphatic raw material, selected from the group consisting of raw phosphate rock ore, phosphate rock concentrates, phosphatic byproducts and phosphatic ...

Dec 01, 2003· At Tessenderlo''s phosphate plant in Ham, in northern Belgium, phosphate rock is turned into a very pure dihydrated crystalline dicalcium phosphate. This isn''t the only method the group uses to make feed phosphates. Intimate knowledge of all available phosphates, claim the company''s experts, is the secret to good phosphorus nutrition for all species of livestock.

Dicalcium phosphate is the calcium phosphate with the formula CaHPO 4 and its dihydrate. The "di" prefix in the common name arises because the formation of the HPO 4 2– anion involves the removal of two protons from phosphoric acid, H 3 PO 4 .

Oct 02, 2019· Dicalcium phosphate (DCP) is a dibasic calcium phosphate formed by a reactive combination of calcium oxide and phosphoric acid. As a dietary supplement, it is commonly used as a source of calcium and phosphorus for both humans and animals. In this role, the compound is either used as an additive in the preparation of cereal and grain products or purchased as a meal supplement.

Orthopedic surgeons use dicalcium phosphate during bone grafts. A May 2018 paper in EFORT Open Reviews noted that this chemical closely resembles natural bone. This similarity gives doctors new options for blending synthetic and real bone to create a strong matrix for the healing process. Synthetic bone also allows drug delivery to the healing ...

The process of making monocalcium phosphate, which comprises adding a phosphoric acid solution to hydrated lime in an amount insufficient to completely neutralize the phosphoric acid solution while thoroughly kneading the pasty mixture, at a temperature in excess of 1800 F., thereafter adding a further amount of hydrated lime in an amount ...

Monocalcium phosphate is an inorganic compound with the chemical formula Ca(H 2 PO 4) 2 ("AMCP" or "CMPA" for anhydrous monocalcium phosphate). It is commonly found as the monohydrate ("MCP" or "MCPM"), Ca(H 2 PO 4) 2 ·H 2 O. Both salts are colourless solids. They are used mainly as superphosphate fertilizers and are also popular leavening agents.

For example, decrease of P205 yields calcium monophosphate monohydrate or increase of P205 and increase of CaO yield dicalcium phosphate. In the process of the present invention it is desirable to operate, generally speaking, in the area of composition on that side of the compositional lines lying toward the P20s apex.

Oct 26, 1976· The invention relates to a combined process for the manufacture of feed grade dicalcium phosphate and pure phosphoric acid. The process comprises the reaction of an excess of phosphate rock with aqueous solutions of a mineral acid selected from hydrochloric acid, phosphoric acid and nitric acid, characterized by the fact that the free acidity of the dissolution liquor does not exceed 60% and ...
