Abstract: Fe2O3, Cr2O3, MnO and NiO were used as raw materials to prepare Fe-Cr-Ni-Mn black ceramic pigments by solid-phase synthesis method. The prepared pigments were analyzed by using X-ray diffractometer (XRD), colorimeter, scanning electron microscope (SEM), ultraviolet-visible (UV-Vis) spectrophotometer and other analytical methods to study the effects of raw material ratio, sintering temperature, holding time and cooling method on the coloring performance of pigments. The results show that when the molar ratio of Fe2O3, Cr2O3, MnO and NiO is 6:1:1:1, the sintering temperature is 1 150 ℃, the holding time is 45 min, and the cooling method is furnace cooling, the particle size of the prepared pigment is fine and uniform distribution, and the L*, a* and b* values are 18.02, 0.20 and 0, respectively. The forbidden band width of the prepared pigment is 1.25 eV, and the color is pure black. In addition, the phases of pigment are mainly composed of NiFe2O4, NiCr2O4 and Ni[Mn0.5Cr1.5]O4. When the prepared pigment is applied to the black ceramic glaze, the glaze surface is pure black, smooth and compact, indicating that the pigment has excellent coloring properties and application potential.
