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 42– anion involves the removal of two protons from phosphoric acid, H 3 PO 4. It is also known as dibasic calcium phosphate or calcium monohydrogen phosphate.
Calcium phosphates are white solids of nutritional value [2] and are found in many living organisms, e.g., bone mineral and tooth enamel. [3] In milk, it exists in a colloidal form in micelles bound to casein protein with magnesium, zinc, and citrate –collectively referred to as colloidal calcium phosphate (CCP). [4]
Monocalcium phosphate is an inorganic compound with the chemical formula Ca(H 2 PO 4) 2 ("AMCP" or "CMP-A" for anhydrous monocalcium phosphate). It is commonly found as the monohydrate ("MCP" or "MCP-M"), 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 ...
Ca 10−δ (PO 4) 6−δ (HPO 4) δ (OH) 2−δ → (1−δ) Ca 10 (PO 4) 6 (OH) 2 + 3δ Ca 3 (PO 4) 2. β-TCP can contain impurities, for example calcium pyrophosphate, Ca 2 P 2 O 7 and apatite. β-TCP is bioresorbable. The biodegradation of BCP involves faster dissolution of the β-TCP phase followed by elimination of HA crystals. β-TCP does ...
Phosphorus pentoxide is a chemical compound with molecular formula P 4 O 10 (with its common name derived from its empirical formula, P 2 O 5). This white crystalline solid is the anhydride of phosphoric acid. It is a powerful desiccant and dehydrating agent.
Calcium phosphide (CP) is the inorganic compound with the formula Ca 3 P 2. It is one of several phosphides of calcium, being described as the salt-like material composed of Ca 2+ and P 3−. Other, more exotic calcium phosphides have the formula CaP / Ca 2 P 2, CaP 3, and Ca 5 P 8. Ca 3 P 2 has the appearance of red-brown crystalline powder or ...
The last one is pyrophosphate [P 2 O 7] 4−. The pyrophosphates are mostly water-soluble. Likewise, tripolyphosphoric acid H 5 P 3 O 10 yields at least five anions [H 5−k P 3 O 10] k−, where k ranges from 1 to 5, including tripolyphosphate [P 3 O 10] 5−. Tetrapolyphosphoric acid H 6 P 4 O 13 yields at least six anions, including ...
Apatite is a group of phosphate minerals, usually hydroxyapatite, fluorapatite and chlorapatite, with high concentrations of OH −, F − and Cl − ion, respectively, in the crystal. The formula of the admixture of the three most common endmembers is written as Ca 10 (PO 4) 6 (OH,F,Cl) 2, and the crystal unit cell formulae of the individual ...
