TiO2 Coating onto Fe Powders via Fluidized Bed CVD
The present research work describes deposition of titania onto Fe powder using a homemade fluidized bed CVD reactor and titanium tetrachloride as the precursor. The as-deposited particles were examined in terms of microstructure and magnetic behavior by means of SEM, XRD, FTIR and VSM. It was realized that high quality TiO2 deposition onto iron particles was possible. The produced thin films were microcrystalline and homogenous, with the optimum conditions being in the range of 800-900 OC and a TiCl4:air ratio equal to 1:15-1:25.
