Characterization of TiO₂ Coating Deposited on Ceramic Substrate

Abstract:

The deposition of titanium dioxide, TiO₂, films on ceramic tiles was studied in order to take benefit of its antimicrobial properties for suitable application in related fields. In this paper, the characteristics of TiO₂ coating deposited on unglazed ceramic substrates with high surface roughness were investigated. TiO₂ films were deposited several times via dip coating sol-gel technique and heat treated at 500oC for 1 hour. The coating morphologies and thickness were analyzed using Scanning electron microscope (SEM), while the crystalline phases were characterized using Glancing angle X-ray Diffraction (GAXRD). Results show that it produces coating with homogeneous morphology, thicker film and with the presence of anatase and rutile phases. It was also observed that one dipping time is sufficient to produce a continuous coating with thickness of ~ 12 μm on average.
