초록
본 연구에서는 Fe2O3-CoO-Cr2O3-MnO2계 색상의 무기안료를 공침법을 사용하여 합성하였다. 출발원료로는 FeCl3, CoCl2, CrCl3, MnCl2를 사용하였으며 침전제로는 2 N-KOH를 사용하였다. MnCl2는 10 mole%로 고정한 후 세 가지 원료로 서 6가지 조성비를 만들어 안료를 합성하였다. 조합된 시료는 1.5시간 1350 o C에서 하소하였다. XRD, FT-IR, SEM 과 UV spectrophotometer를 사용하여 안료의 특성 분석을 하였다. 합성된 안료는 석회유, 석회 바륨유에 각각 6 wt%씩 첨가하여 1260 o C 산화소성, 1240 o C 환원 소성하였다. UV Spectrometer를 사용하여 색상분석을 한 결과는 black, bluish black, dark grayish green을 나타냈다.9
Abstract
The inorganic pigments of Fe2O3-CoO-Cr2O3-MnO2 were synthesized by the co-precipitation method. FeCl3,CoCl2, CrCl3 and MnCl2 are used for the starting raw materials, and 2 N-KOH for precipitator. MnCl2 is secured with 10mole%, and 6 composition ratios are used with thre ingredients to synthesize the pigments. The samples were calcined at1350oC/1.5 h. The resulting pigments were characterized by using XRD, FT-IR, SEM, and UV spectrophotometer. 6 wt%pigments were applied to lime glaze and lime-barium glaze respectively firing at 1260oC for oxidation atmosphere and1240oC for reduction one. The results of color analysis by using UV spectrophotometer showed black, bluish black anddark grayish green.Key words Co-precipitation method, Color, Pigments.... ..
