Fig. 1 shows the XRD patterns of SiC–TiO2 samples prepared by
sol–gel method and after thermal treatment at 450 ◦C. According
to XRD results, the presence of only TiO2 (anatase phase) and SiC is
detected in all samples. The presence of anatase is more evident as
the amount of TiO2 increases (SG3 > SG2 > SG1), while intensity of
SiC peaks decreases as SiC content decreases
