以钙铋氧化物为原料，合成了新型绿色无机红色颜料Ca3（Bi1−xREx）8O15（RE = Sc3+，Er3+，Y3+，Ho3+，Dy3+），并对其呈色性能进行了表征。这些颜料的颜色取决于组成和合成条件，其中Ca3（Bi0.93Y0.07）8O15样品在800 °C下煅烧3次，反应时间为2h，得到的红色最鲜艳。该颜料对应于亮度和红色色度的L * 和 * 值分别为45.6和+30.6，大于市售Fe2O3颜料的L* = 38.4，a * = +29.5。由于该颜料由无毒和安全的元素组成，因此它应该是常规Fe2O3颜料的有吸引力的替代品。
Novel environmentally friendly inorganic red pigments based on calcium bismuth oxide, Ca3(Bi1−xREx)8O15(0 ⩽x⩽ 0.09; RE = Sc3+, Er3+, Y3+, Ho3+and Dy3+), were successfully synthesized and the color properties were characterized. The color of these pigments depended on the composition and the synthesis condition, and the most vivid red color was obtained for the Ca3(Bi0.93Y0.07)8O15sample calcined thrice at 800 °C for 2 h. TheL* anda* values corresponding to brightness and red chromaticity for this pigment were 45.6 and +30.6, respectively, which were greater than those of a commercially available Fe2O3pigment (L* = 38.4,a* = +29.5). Since the present pigment is composed of nontoxic and safe elements, it should be an attractive alternative to the conventional Fe2O3pigment.
