Bulk TiO2-P2O5 glasses containing various amounts of TiO2 were successfully prepared by the sol-gel process followed by calcination at various temperatures. Influence of processing parameters on the formation of homogeneous and transparent glasses were investigated. Effect of calcination temperature on the crystal phases developed, their size, morphology, and surface area were investigated through XRD, DTA-TG, SEM, and BET analyses. Results revealed that by heat-treating the sol-gel derived gels, TiO2-P2O5 glasses could be successfully produced. It has been realized that photocatalytic activity of the glass containing 90 mol% TiO2 and calcined at 600 ºC for 2 h was comparable with that of P25 powder.
