 · Dicalcium phosphate is used as a food additive, it is found in some toothpastes as a polishing agent and is a biomaterial. Dibasic calcium phosphate is produced by the neutralization of calcium hydroxide with phosphoric acid, which precipitates the dihydrate as a solid. At 60°C the anhydrous form is precipitated: H3PO4 + Ca (OH)2 → CaHPO4

The dicalcium phosphate thus obtained contains 44–47% total P2O5 and can be used as fertilizer or, with an additional low pH filtration step, as animal feed supplement. This paper presents results laboratory experiments to test a new process for manufacture of dicalcium phosphate. The process is based on the nitric acidula

It is thought that dicalcium phosphate may undergo molecular reorientation to form a non-crystalline amorphous calcium phosphate which acts as an intermediate in the process. Analysis of synthetic amorphous calcium phosphate indicates that it is composed of 1 nm diameter Ca 9 (PO 4 ) 6 clusters which close-pack randomly to form 30–80 nm spheres.
