Green glazes were successfully prepared using ferrochromium slag waste as chromium and iron precursors by introducing Co₂O₃ as coloring agent. The performance of the glazes was investigated by XRD, EDS, FT-IR, and UV-vis. A chromatic mechanism was proposed to explain the variation of glaze colors with the increase of Co₂O₃ content. The results showed that the Co-doped glazes had Co-Fe-Cr mixed spinel-type structures when Co-doped contents were 0.5–1.5 wt%. Green glazes could be prepared by adjusting the blue component (Co²⁺) proportion, which was achieved with different amounts of Co₂O₃, to balance the color proportion of blue and yellow in glazes according to subtractive color process. The intensity of green color in glaze samples was related to the presence of d-d transitions of tetrahedral Fe³⁺, ⁴A₂(F) → ⁴T(P) of tetrahedral Co²⁺, and ⁴A_2g → ⁴T_2g of octahedral Cr³⁺ in spinel structures. These results indicated that environment-friendly, Co-doped, spinel-type structured, coloring agents, prepared using ferrochromium slag waste, can be applied to produce green glazes or inkjet printer ink as well as to provide a means for preparing green glaze using ferrochromium slag waste.

通过引入铬铁渣废料作为铬和铁的前体，通过引入Co ₂ O ₃作为着色剂，成功制备了绿色釉料。通过XRD，EDS，FT-IR和UV-vis研究了釉的性能。提出了一种彩色机制来解释釉颜色随Co ₂ O ₃含量的增加而变化。结果表明，当Co掺杂量为0.5〜1.5 wt％时，Co掺杂釉具有Co-Fe-Cr混合尖晶石型结构。可以通过调节蓝色成分（Co ²⁺）的比例来制备绿釉，这是通过使用不同量的Co ₂ O _{3实现的。}，根据减色法来平衡釉中蓝色和黄色的颜色比例。釉料样品中绿色颜色的强度与存在DD四面体的Fe的过渡³⁺，⁴阿₂（F）→  ⁴ Ť四面体的Co（P）²⁺，和⁴甲_2克 →  ⁴ Ť _2克的八面体铬³⁺在尖晶石结构中。这些结果表明，使用铬铁矿渣废料制备的环保，共掺杂，尖晶石型结构化着色剂可用于生产绿色釉料或喷墨打印机油墨，并提供使用铬铁合金制备绿色釉料的方法。炉渣浪费。
