The XRD studies revealed that the addition of Ni and Fe enhances the rutile transformation and above 4 wt.% leads to formation of new phase such as TiNiO3 (ICDD File No: 04-010-7291) and TiFeO3 (ICDD File No: 04-007-2813) respectively. The addition of Nb, on the other hand, stabilizes the anatase phase.
