Di-calcium phosphate by direct acidulation of phosphate rockiv. ABSTRACT. An investigation was undertaken to develop a process for producing di-calcium phosphate by direct acidulation of phosphate rock. In general, when phosphate rock is treated with sulfuric acid, mono-calcium phosphate or phosphoric acid is formed. If less sulfuric acid is used, di-calcium phosphate should be.process for making dicalcium phosphate from rock phosphate,Process for producing phosphoric acid and dicalcium phosphateThis is a continuation of application Ser.

Dicalcium phosphate - Wikipedia

Dicalcium phosphate is the calcium phosphate with the formula CaHPO4 and its dihydrate. The "di" prefix in the common name arises because the formation of the HPO42– anion involves the removal of two protons from phosphoric acid, H3PO4. It is also known as dibasic calcium phosphate or calcium monohydrogen.
