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.
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 ...
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 ).
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 chloride: [citation needed] CaCl 2 + H 4 P 2 O 7 (aq) → Ca 2 P 2 O 7 ·2 H 2 O + HCl. The anhydrous forms can be prepared by heating dicalcium phosphate: [2] 2 CaHPO ...
Dipotassium phosphate (K 2 HPO 4) (also dipotassium hydrogen orthophosphate; potassium phosphate dibasic) is the inorganic compound with the formula K 2 HPO 4. (H 2 O) x (x = 0, 3, 6). Together with monopotassium phosphate (KH 2 PO 4. (H 2 O) x), it is often used as a fertilizer, food additive, and buffering agent. [1]
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 minerals are written as Ca 10 (PO 4) 6 (OH) 2, Ca 10 (PO 4) 6 F 2 and Ca 10 (PO 4) 6 Cl 2.
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 ...
CDHA is sometimes termed "apatitic calcium triphosphate." [1] [3] [4] The composition of amorphous calcium phosphate is Ca x H y (PO 4) z ·nH 2 O, where n is between 3 and 4.5. CDHA has a general formula of Ca 9 (HPO 4)(PO 4) 5 (OH). [4] Precipitation from a moderately supersaturated and basic solution of a magnesium salt produces amorphous ...
