• To investigate color properties by inclusion of hematite in the iron zircon pigments, different samples were prepared by the sol-gel method without mineralizer. The starting amount of the ferric salt in the sol-gel reacting mixture was varied in order to obtain Fe_2O_3/Zr molar ratio in the range of 5-30%. Fe-ZrSiO_4 pigments of the sol-gel reaction were calcined the range 600-1300℃. The crystalline phases were determined by using X-ray diffraction(XRD). The process of inclusion of hematite in iron zircon pink color were studied by UV-Vis-NIR spectroscopy and FT-IR spectroscopy. It was found that the coral pink and reddish color in the iron zircon pigments is due to α-Fe_2O_3 particles incorporated in the zircon matrix.
