چکیده مقاله:

The crystallization behavior and photocatalytic properties of the sol-gel derived glass ceramic coatings in the TiO۲-SiO۲-B۲O۳ system were studied. the prepared sol was sprayed on a glazed ceramic wall. Following drying, the coated specimens were fired at ۹۰۰°C for ۱ h. The impact of boron oxide content in the composition was explored in terms of anatase stability and glass maturing temperature. The thermal and crystallization behaviors of the dried gels were studied by the STA, XRD, and FESEM. The photocatalytic property of the coated layer was examined using methylen blue degradation. Based on the results, the sample containing ۱۵ wt% of boron oxide demonestrated about  ۳۰% dye removal efficiency, after only ۶۰ min of UV-irradiation. Additionally, this particular sample exhibited the greatest magnitude of the anatase phase in comparison to the other samples.
