Feb 06, 2001· Production of dicalcium phosphate or monocalcium phosphate from calcium phosphate . United States Patent . Abstract: 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 .
It is thought that dicalcium phosphate may undergo molecular reorientation to form a noncrystalline 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 closepack randomly to form 30–80 nm spheres.
Dicalcium phosphate is a crystalline feed grade Dicalcium phosphate containing % Minimum phosphorous and % Maximum calcium. The selected raw material of nonanimal origin and the production process ensures an end product with good phosphorous digestibility and a content of undesirable elements well below that stipulated by EU feed legislation.
