WO2004076348A1 A process for the manufacture of

This invention relates to the preparation of feed grade dicalcium phosphate from a source containing monocalcium phosphate such as super phosphate, concentrated super phosphate and the like. The first step consists of leaching water soluble mono calcium phosphate therefrom with water or recycle wash water from one of the subsequent steps.

US3988420A Processes for the manufacture of feed

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

Dicalcium Phosphate an overview ScienceDirect Topics

Dicalcium Phosphate. Dicalcium phosphates are one of the fastest resorbable CaP materials with the re-sorption rate of DCPD at a pH of 5.5 being approximately three times and three hundred times faster than that of TCP and carbonated HAp, respectively (Tang et

Production of dicalcium phosphate by treatment of

高达10%返现 This paper presents results laboratory experiments to test a new process for manufacture of dicalcium phosphate. The process is based on the nitric acidulation of phosphate rock concentrate, followed by neutralization of the extract liquor with calcium carbonate. The precipitated dicalcium phosphate is then separated from calcium nitrate solution by filtration. The dicalcium phosphate

Dicalcium-Phosphates- Process, Technology, Applications

Dicalcium phosphate crystals are precipitated and after filtration and drying the resulting product is a very pure crystalline dihydrate dicalcium phosphate that is sold as Aliphos® Dical. Dicalcium phosphate is obtained from degreased bones which are demineralised by hydrochloric acid treatment and precipitated by a saturated lime solution.

Effect of pH on the Structure of Calcium Phosphate

Oct 10, 2019 高达10%返现 At pH < 6, rectangular disk-shaped dicalcium phosphate anhydrous (DCPA) microcrystals were formed; on the other hand, at pH > 8, hydroxyapatite (HA) nanorods were predominantly formed. This can be explained by a self-setting mechanism associated with the role of hydroxide species during the hydrothermal process.
