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 ...
This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium.

The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
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 4 2– 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.
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 ).
The calcium phosphate is encapsulated in the casein micelles in the form of small nanoclusters, which can be considered protein-based carriers for calcium phosphate. The calcium phosphate in the casein micelles is in an amorphous form and solubilizes when the pH is reduced; at pH less than 5, all calcium phosphate in milk is solubilized; under ...
Crystals of the tetrahydrate can be prepared by treating a solution of sodium pyrophosphate with calcium nitrate with careful control of pH and temperature: [3] Na 4 P 2 O 7 (aq)+2 Ca(NO 3) 2 (aq)→ Ca 2 P 2 O 7 ·4 H 2 O + 4 NaNO 3. The dihydrate, sometimes termed CPPD, can be formed by the reaction of pyrophosphoric acid with calcium ...
