| Summary: | Hydroxyapatite is a ceramic material which is known as a highly bioactive and biocompatible material. It can be extracted
from natural resources such as bovine bone. In the present study, hydroxyapatite composites with different percentage of
sodalime glass were made and sintered at different temperatures. Finally, the specimens were evaluated with respect to
bioactivity tests in simulated body fluid (SBF). Micrographs of scanning electron microscopy (SEM) showed that calcium
phosphate precipitated on biocomposites surfaces. SEM images and XRD analysis showed that the composite with 5 % glass
additive sintered at 1200oC has excellent capacity to form apatite layer on its surface. |
