Synthesis of nano hydroxyapatite powder that simulate teeth particle morphology and composition

A simple sol–gel precipitation technique to synthesize nano hydroxyapatite (HA) particles (∼30 nm) that show similar morphology, size and crystallinity to HA crystals of human teeth is reported. Calcium nitrate tetrahydrate and potassium dihydrogenphosphate were used as calcium and phosphorus precursors, respectively. Double distilled water was used as a diluting media for HA sol preparation and ammonia was used to adjust the pH to 11. After...
