The ultrasound effect on the morphological properties of hydroxyapatite

Abstract

The present study considers the morphological and dispersity characteristics of hydroxyapatite (HAp) samples synthesised through the ultrasound-Assisted hydrothermal method with additional pressure treatment. The samples were analyzed by the X-Ray diffraction, scanning electron microscopy, low-Temperature nitrogen adsorption. The ultrasound effect on the HAp morphologiy and dispersity was studied. The pressure assisted ultrasonic treatment made possible obtaining HAp samples with different morphology from rods and flakes to particles with irregular shape close to spherical. Also pressure assisted ultrasonic treatment able to increase the porosity of HAp materials.
