Calcium phosphate stones account for approximately 15% of kidney stone disease. Calcium phosphate stones tend to grow in alkaline urine, especially when Proteus bacteria are present. It is the most common type in pregnant women. [6] Calcium phosphate is the usual constitution of microcalcifications of the breast, particularly dystrophic ...
The anhydrous forms can be prepared by heating dicalcium phosphate: [2] 2 CaHPO 4 → Ca 2 P 2 O 7 + H 2 O. At 240-500 °C an amorphous phase is formed, heating to 750 °C forms β-Ca 2 P 2 O 7, heating to 1140 - 1350 °C forms the α-Ca 2 P 2 O 7.
Tricalcium phosphate (sometimes abbreviated TCP), more commonly known as Calcium phosphate, is a calcium salt of phosphoric acid with the chemical formula Ca 3 (PO 4) 2. It is also known as tribasic calcium phosphate and bone phosphate of lime (BPL). It is a white solid of low solubility.
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.
Amorphous calcium phosphate (ACP) is a glassy solid that is formed from the chemical decomposition of a mixture of dissolved phosphate and calcium salts (e.g. (NH 4) 2 HPO 4 + Ca(NO 3) 2). The resulting amorphous mixture consists mostly of calcium and phosphate, but also contains varying amounts of water and hydrogen and hydroxide ions ...
Tetracalcium phosphate is a component used in the formation of some hydroxyapatite calcium phosphate cements that used for the repair of bone defects. [3] One example of a hydroxyapatite cement forming reaction is that of tetracalcium phosphate and dicalcium diphosphate dihydrate: [4] Ca 4 (PO 4) 2 O + CaHPO 4 ·2H 2 O → Ca 5 (PO 4) 3 (OH ...
As an example of the wide range of solubility of calcium compounds, monocalcium phosphate is very soluble in water, 85% of extracellular calcium is as dicalcium phosphate with a solubility of 2.00 mM, and the hydroxyapatite of bones in an organic matrix is tricalcium phosphate with a solubility of 1000 μM.
