FABRICATION AND ANALYSIS OF THE EFFECT OF DOPING TIO2 IN 1393 BIOACTIVE GLASS.

From the previous studies on bioactive glasses it was suggested that assimilating small quantities of TiO2 may result in an increase in the bioactivity and hydroxyapatite formation. Titanium is present in several inert biomaterials such as hip prosthesis made of titanium, screws and plates to repair bone damages. It does not induce an inflammatory response because it is a good biocompatible material. It is also used in the materials for aerospace because it has good mechanical properties. It allows reinforcing biomaterials.1393 Bioactive Glass in addition to TiO2 (x=0-2.5%) was prepared by melting quenching technique, the present work explores the effects of titanium oxide additions. Bioactivity of the glass samples was assessed through their hydroxyapatite formation ability by immersing them in the simulated body fluid (SBF) for different soaking periods. The formation of hydroxyapatite was confirmed by FTIR spectrometry, pH measurement and microstructure evaluation through Scanning Electron Microscopy (SEM). Densities and mechanical properties of the samples were found to increase considerably with an increase in the concentration of titanium oxide.
