| Abstract: | Nanometer-size needle-like hydroxyapatite (HA) crystals were prepared by a wet chemical
precipitation method at atmospheric pressure using ultrasonic technique. Effects of ultrasonic treatment on crystal morphology and size of HA under different process conditions are studied by controlling the daration of ultrasonic treatment and the content of dispersants. Ultrasonic treatment can effectively improve preparation of nanometer-size needle-like hydroxyapatite (HA) crystals that are similar to HA crystal of human bone. |
