Biomimetic desposition of hydroxyapatite coating on hollow glass microspheres

Jiao Yan

Abstract

Hollow glass microspheres were pretreated by NaOH and bioactive glass successively,and then soaked in 1.5 SBF at 36.5 ℃ for 15 days.The phase composition and morphology were characterized by X-ray diffractometer(XRD),scanning electron microscope(SEM) and field emission scanning electron microscope(FESEM),respectively.The results show that the formed HA coating was uniform and dense after being soaked for 15 days with SBF,and the thickness of the coating increased with the soaking time.
