The effects of dopant content and calcination temperature on Mn-Doped ZrTiO4 structure and properties were successfully investigated. Composite of Mn-doped zirconium titanate was synthesized by sol-gel method. Titanium isopropoxide was used as precursor of TiO2, while zirconia powder was used as another semiconductor, and MnCl2.4H2O was the source of dopant. Various amounts of manganese were incorporated into ZrTiO4 and calcination was performed at temperatures of 500, 700 and 900 °C. Synthesized composites were characterized by Fourier-transform infrared spectroscopy (FTIR), specular reflectance UV-Vis spectroscopy (SRUV), X-ray diffraction method (XRD) and scanning electron microscopy equipped with X-ray energy dispersive spectroscopy (SEM-EDX). The results showed that optimal amount of Mn dopant could shift the absorption edge of ZrTiO4 to visible range and the coupling of zirconia inhibit the phase transformation of titania.
