Abstract:
Bioglass® (45S5) was prepared by conventional melting process and hydroxyapatite (HA) was prepared by sol-gel method. The
bioglass (45S5) and hydroxyapatite (Ca10(PO4)6(OH)2) samples were mixed in a particular proportion to prepare composite
by using hydraulic pressing. Based on thermogravimetric and differential thermal analysis, the composite were sintered with
a suitable heat treatment process at 1000-1050°C. The in-vitro bioactivity of samples was determined in simulated body fluid
for 1, 3, 7, 14 and 21 days. The bioactivity was examined in vitro with respect to the ability of hydroxyapatite layer formation
on the surface of samples when they were immersed in simulated body fluid (SBF). DTA/TGA, XRD, SEM and mechanical
studies were conducted for different characteristic measurement of biocomposites. The result shows the enhancement in
bioactivity and mechanical properties of (45S5-HA) biocomposites for clinical implantation.
