초록

본 연구에서는 $Fe_2O_3-CoO-Cr_2O_3-MnO_2$계 색상의 무기안료를 공침법을 사용하여 합성하였다. 출발원료로는 $FeCl_3,\;CoCl_2,\;CrCl_3,\;MnCl_2$를 사용하였으며 침전제로는 2N-KOH를 사용하였다. $MnCl_2$는 10 mole%로 고정한 후 세 가지 원료로서 6가지 조성비를 만들어 안료를 합성하였다. 조합된 시료는 1.5시간 $1350^{\circ}C$에서 하소하였다. XRD, FT-IR, SEM 과 UV spectrophotometer를 사용하여 안료의 특성 분석을 하였다. 합성된 안료는 석회유, 석회 바륨유에 각각 6wt%씩 첨가하여 $1260^{\circ}C$ 산화소성, $1240^{\circ}C$ 환원 소성하였다. UV Spectrometer를 사용하여 색상분석을 한 결과는 black, bluish black, dark grayish green을 나타냈다.

The inorganic pigments of $Fe_2O_3-CoO-Cr_2O_3-MnO_2$ were synthesized by the co-precipitation method. $FeCl_3,\;CoCl_2,\;CrCl_3\;and\;MnCl_2$ are used for the starting raw materials, and 2 N-KOH for precipitator. $MnCl_2$ is secured with 10 mole%, and 6 composition ratios are used with three ingredients to synthesize the pigments. The samples were calcined at $1350^{\circ}C/1.5h$. The resulting pigments were characterized by using XRD, FT-IR, SEM, and UV spectrophotometer. 6wt% pigments were applied to lime glaze and lime-barium glaze respectively firing at $1260^{\circ}C$ for oxidation atmosphere and $1240^{\circ}C$ for reduction one. The results of color analysis by using UV spectrophotometer showed black, bluish black and dark grayish green.
