发现通过常规固态反应方法制备的氧化物系统Sc2− xFexO 3的颜色从众所周知的红色（x = 2.0）变为黄色（x ≤ 0.6），并且在0.2 ≤x≤ 0.4时变为绿黄色。根据该系统的结构表征结果，在1.6 ≤x≤ 2.0时，双相双相区持续存在，而在0 ≤x≤ 1.0时，方铁锰矿型相为双相。1.2 ≤x≤ 1.4的中间区域是混合区域。由于绿色是氧化铁的罕见颜色，因此将最典型组成的粉末（x= 0.4，（L*，a*，B*）坐标为（77.3，−0.5，51.0））作为日式绘画的颜料进行测试，并作为瓷器上的釉上彩瓷漆进行测试;获得了相当好的结果。
An oxide system Sc2−xFexO3prepared by a conventional solid-state reaction method was found to change its color from the well-known reddish color atx= 2.0 to a yellowish color atx ≈0.6 and to a greenish-yellow color at 0.2 ≤x≤ 0.4. According to the structural characterization results for this system, the monophasic corundum phase region persists for 1.6 ≤x≤ 2.0, whereas the bixbyite-type phase is monophasic for 0 ≤x≤ 1.0. The intermediate region of 1.2 ≤x≤ 1.4 is a mixed region. Because green is a rare color for iron oxides, powder of the most typical composition,x= 0.4, with (L*,a*,b*) coordinates of (77.3, −0.5, 51.0) was tested as a pigment for a Japanese-style painting and also as an overglaze enamel on porcelain; reasonably good results were obtained.
