| ABSTRACT |
|
The Rutile - type brown pigments doped with chromium were synthesized. Samples of $Ti_{1-x}Cr_xO_2$ ($0.02{leq}X{leq}0.08$) were synthesized by the solid state method. Solid solution limit of Cr contents to the rutile structure and its coloration were studied. Optimum composition was investigated accordingly. The characteristics of synthesized pigments were analyzed by XRD, SEM, Raman spectroscopy and UV. As a result, single phase of Rutile was observed from $1000^{circ}C$ by XRD. The maximum limit of solid solution was 0.06 mole $Cr_2O_3$. The glazed sample showed brown color, and the value of CIE $L^*a^*b^*$ was $L^*$ 33.27, $a^*$ 10.64, $b^*$ 20.84. |
