What is Calcium Phosphate?

Calcium phosphate is a calcium salt the phosphoric acid through a chemistry formula Ca3(PO4)2. That is likewise known together Calcium phosphate tribasic or Tricalcium Phosphate.

You are watching: The correct formula for calcium phosphate is

Calcium phosphate appears as a white amorphous or crystalline powder that is odourless and tasteless. The is insoluble in ethanol, acetic acid but soluble in dilute nitric acid and also hydrochloric acid. It slightly dissolves in water. That is found in bones, milk, teeth, and also ground.

Apatite is a mineral absent which is an impure and facility form of calcium phosphate i beg your pardon produces tribasic calcium phosphate. An apatite is a form of phosphorite which has calcium phosphate combined with other compounds.

Calcium phosphates are vital materials in biology, geology, market , medicine and dentistry. That formation, functions and applications rely on its framework , composition, solubility and stability.

Preparation the Calcium Phosphate

It can also be produced by reaction phosphoric acid (H3PO4) with solid calcium hydroxide Ca(OH)2

Ca(OH)2+H3PO4→Ca3(PO4)2+H2O (unbalanced)

3Ca(OH)2+2H3PO4→Ca3(PO4)2+6H2O (balanced equation)

Dibasic calcium phosphate can be created in the former of these reactions by using an aqueous systems of calcium hydroxide. Monobasic calcium phosphate is obtained by including excess phosphoric mountain to one of two people a dibasic equipment or a tribasic calcium phosphate solution and also letting the equipment to evaporate.

Calcium Phosphate Solubility – Ca3(PO4)2

Solubility is among the many important attributes of calcium phosphate salts. That is solubility that specifies the course of number of reactions entailing calcium phosphates such together absorption, precipitation, hydrolysis and phase transformation. Calcium phosphate solubility additionally plays a significant role in biological processes including tough tissue formation and resorption and also pathological calcification.

Calcium phosphate-based bone graft replacements (mostly tricalcium phosphate or hydroxyapatite) room bioceramics that have actually the greatest resemblance come bone minerals. This is what provides calcium phosphate fantastic biocompatibility, biodegradability and osteoconductivity.

Calcium is a mineral found naturally in food. Calcium is necessary for plenty of normal attributes of the body, in certain bone formation and maintenance. Calcium can likewise bind to other minerals (such as phosphate) and aid to extract them from the body. Calcium phosphate is provided to prevent and treat calcium deficiencies. Calcium phosphate may additionally be used for objectives not specified in this medicine guide.

Uses that Calcium phosphate (Ca3(PO4)2)

Calcium phosphate is used as one antacid and also dietary supplement in veterinary medicine.It is used in medicine as calcium replenisher.It is provided as a buffer in food.It is provided stabilizer in plastics.It is offered in the manufacturing of milk glass.It is supplied in the manufacturing of fertilizers.It is provided in the produce of luminescent materials.It is offered to clarify sugar syrups.It is offered in dental powders.

Occurrence of Calcium Phosphate

Calcium and also phosphorus comprise the mass of animal mineral nutrient demands (to satisfy both human body tissue and also milk needs), therefore DCPD is a popular and also commonly used animal supplement. Dicalcium Phosphate Dihydrate is likewise of problem as the is the many soluble of barely soluble calcium phosphate crystals, making that a good choice because that rock phosphate dissolved tests. The fate the DCPD in the floor is fairly temporary.

Mineral phosphorus is usually applied to soil in a water-soluble form, such as triple supervisor phosphate or diammonium phosphate. Together phosphorus dissolves a high concentration of equipment P, precipitation reactions are preferred. Calcium phosphates are found in nature in numerous ways and also are the primary minerals because that the produce of phosphate fertilizers and also for a variety of phosphorus compounds.

Solubility of Calcium Phosphates

Solubility is just one of the most crucial properties of calcium phosphate salts. That is solubility that specifies the food of number of reactions involving calcium phosphates such together absorption, precipitation, hydrolysis and phase transformation. Calcium phosphate solubility additionally plays a vital role in organic processes including hard tissue breakthrough and resorption as well as pathological calcification.

Solubility is conventionally described together the quantity of a solid that can dissolve into a unit volume of solution. With calcium phosphates, this level also varies by countless orders that magnitude, including variations in pH and concentrations the acids and also bases, such as HCI and also NaOH. Water-soluble calcium phosphate is obtained from the skeletons the vertebrate animals. Water soluble calcium phosphate is an essential material for plant growth and is generally dispersed in the soil. Calcium phosphate is insoluble in water yet soluble in acids: the is provided in organic farming. Calcium phosphate might dissolve slightly in CO2-containing water.

Health Hazards linked with Calcium Phosphate

When the toxic doses ingested become an ext than 2 g/kg unexplained skin sensitization occurs. Inhaling the may reason chemical pneumonitis. Calcium phosphate is provided in many assets in biomedicine, but also in dentistry and also cosmetics. In certain situations, that is found in nanoparticle form, either on function or after destruction or mechanical abrasion. Possible issues describe the biological influence of these nanoparticles.

A thorough literature review mirrors that calcium phosphate nanoparticles, as such, perform not have inherent toxicity, but may lead to rise in intracellular calcium concentration following endosomal uptake and lysosomal degradation. However, cells are able to eliminate calcium from the cytoplasm within a few hours, unless an extremely high doses of calcium phosphate space used.

The cytotoxicity observed in some cell culture studies , specifically for unfunctionalized particles, is likely because of particle agglomeration and also subsequent precipitate on the cabinet layer, resulting in a an extremely high local concentration that particles, high absorption of particles, and subsequent cabinet death.

Calcium phosphate nanoparticles have the right to reach the bloodstream by inhalation, but no harmful effects have to be observed through the exception of extended exposure come high bit doses. Calcium phosphate nanoparticles in ~ the body execute not pose a risk since they are typically resorbed and destroyed through osteoclasts and also macrophages.


It can be used to law disorders brought about by short levels that calcium such as bone loss (osteoporosis), weak skeletal (osteomalacia / rickets), diminished parathyroid gland function (hypoparathyroidism), and also some muscle disease (latent tetanus).


Calcium can make such drugs more challenging for her body come absorb. Calcium phosphate functions far better when the taken v food. And also ensure that you can take calcium phosphate safely, educate your doctor if you have any type of of the adhering to conditions: a history of kidney stones.


Method of creating calcium phosphate fertilizer from a calcium-containing material, reactive through diluted phosphoric mountain to produce calcium phosphate fertilizer, calcium silicate and diluted phosphoric mountain consisting of mixing the fine calcium-containing material with diluted phosphoric mountain containing by load of H3PO4 at the very least 30 to 40 every cent.
