Abstract
The research was began with the synthesis of magnetite by reacting FeCl3.6H2O and FeSO4.7H2O by co-precipitation and sonication method. Then magnetite covered by silica was sintisized using sonication method by reacting TEOS with magnetit in base condition, and then coated by TiO2 using sol-gel method followed by calcination by using TTIP as a precusor. The X-Ray Diffractometer (XRD) were used to characterize the nanoparticles. The XRD defractofram showed the diffraction pattern 2ÆŸ (o) at 25.38o, 35.881o, 38o, 38,797o, 48.26o, 54.22o, 55,4o, 63.119o, and 69.24o that based on JCPDS data No. 21-1272 that showed TiO2 anatase stucture.
