ABSTRACT |
To study the effect of color development of Ni-doped willemite blue pigments, five batches of compositions were prepared and fired at $1350^{circ}C$/hold for 1 h. When Ni was substituted for ZnO by 0.03 mole the optimum result were obtained. Then they were fired at $1300^{circ}C$ and held for 1, 2, 4 and 6 h respectively for the purpose sake. XRD, Raman spectroscopy, FT-IR, UV-vis were used to analyze the results of experiment. The substitution of 0.03mole Ni for Zn was most optimum and which produced good willemite at the temperature of $1300^{circ}C$, holding for 6 h. In ceramic arts, cobalt has been used for blue coloring, in most cases, despite of its high cost. If the low cost Ni-doped willemite blue pigments supplies for them with stable and multiple shades of blue pigment, using NiO at high temperature, it would provide various blues for ceramic wares. |
