What is the chemical reaction employing calcium hydroxide and hydrogen phosphate, yielding nanocrystals of Hydroxyapatite, known? Correct Answer Wet chemical deposition
Wet chemical deposition is the most common method of preparation of Hydroxyapatite (calcium phosphate) nanoparticles. Reaction for the above method is given below: 10Ca(OH)2 + 6H3PO4 ➝ Ca10 (PO4)6(OH)2 + 18H2O The temperature of the reaction plays an important role in determining the crystalline size. Synthesis carried out at temperature lower than 60°C results in monocrystalline nanoparticles, whereas at higher temperature polycrystalline nanoparticles are obtained.
