It is also known as tribasic calcium phosphate and bone phosphate of lime (BPL). Most commercial samples of "tricalcium phosphate" are in fact hydroxyapatite. It is a white amorphous powder and non-flammable. Tricalcium phosphate can be produced commercially by treating hydroxyapatite with phosphoric acid and slaked lime. https://padlet.com/vekes/228yfhnlt5t354y6/wish/2214430974 -Han]]> 2022-06-08 03:42:17 UTC https://padlet.com/vekes/228yfhnlt5t354y6/wish/2214430974 Tricalcium Phosphate (TCP) https://padlet.com/vekes/228yfhnlt5t354y6/wish/2214431290 Tricalcium phosphate is produced commercially by treating hydroxyapatite with phosphoric acid and slaked lime. 
  • Typically double decomposition reactions are employed, involving soluble phosphate and calcium salts, e.g. (NH4)2HPO4 + Ca(NO3)2 is performed under carefully controlled pH conditions. The precipitate will either be "amorphous tricalcium phosphate", ATCP, or calcium deficient hydroxyapatite, CDHA, Ca9(HPO4)(PO4)5(OH), (note CDHA is sometimes termed apatitic calcium triphosphate). 
  • Crystalline tricalcium phosphate can be obtained by calcining the precipitate. β-Ca3(PO4)2 is generally formed, higher temperatures are required to produce α-Ca3(PO4)2.
  • An alternative to the wet procedure entails heating a mixture of calcium pyrophosphate and calcium carbonate.

- To reduce dental hypersensitivity, hydroxyapatite nanocrystals (nHA) have been utilised in toothpaste. 
- They assist to repair and remineralize the enamel, which helps to avoid dental sensitivity.
- Tooth enamel can become demineralised as a result of a variety of factors, including acidic erosion and dental caries. If left untreated, this can result in dentin exposure and, as a result, tooth pulp exposure.

Nano-hydroxyapatite possesses a remineralising effect on teeth; prevent damage from carious attacks.

In the event of an acid attack by cariogenic bacteria, nano-hydroxyapatite particles can infiltrate pores on the tooth surface to form a protective layer.

Hydroxyapatite is a potential adsorbent for the defluoridation of drinking water.
