Following drying, the coated specimens were fired at 900&deg;C for 1 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 15 wt% of boron oxide demonestrated about &nbsp;30% dye removal efficiency, after only 60 min of UV-irradiation. Additionally, this particular sample exhibited the greatest magnitude of the anatase phase in comparison to the other samples.</span></span></span></span></span></span></span><br> &nbsp; sol-gel, photo catalyst , glass-ceramic coating , anatase 1 8 http://ijmse.iust.ac.ir/browse.php?a_code=A-10-2911-2&slc_lang=en&sid=1 Sara Ahmadi sara.ahm92@gmail.com 1800319475328460021109 1800319475328460021109 Yes Construction and Minerals Research Group, Technology and Engineering Research Center, Standard Research Institute, Karaj, Alborz, Iran Bijan Eftekhari yekta eftekhari@iust.ac.ir 1800319475328460021110 1800319475328460021110 No 2Ceramic Division, School of Materials and Metallurgy Engineering, Iran University of Science and Technology, Tehran, Iran Alireza mirhabibi ar_mirhabibi@iust.ac.ir 1800319475328460021111 1800319475328460021111 No School of Chemical and Process Engineering, University of Leeds, LS2 9JT
