Abstract Spinel-type Zn(Fe, Cr)2O4 powders are promising pigments in the ceramic decoration field. In this work, nanocrystalline ZnFe2-xCrxO4 (x = 0, 0.2, 0.4, 0.6, 0.8, 1.0, 1.2, 1.4, 1.6, 1.8, 2.0) were successfully synthesized using combustion method with sucrose as fuel. TG-DTA, XRD, HRTEM, EDS, XRF, FT-IR, and optical techniques were employed to characterize the samples. The as-prepared ZnFe2-xCrxO4 nanocrystallites correspond to a pure spinel phase, and the lattice parameter and crystallite size decrease as the content of Cr increases. The reddish-brown tone of the sample first increases and then diminishes as x increases. When x = 0.8, the sample owns the strongest reddish-brown tone with L* = 41.5, a* = 22.3, and b* = 20.2. The research shows that the ZnFe2-xCrxO4 nanocrystallites have significant advantages in increasing the inks' coloring ability as well as in reducing the energy consumption of inks fabricating processes.

陶瓷数码装饰用ZnFe Cr O4纳米微晶的燃烧合成

摘要 尖晶石型Zn(Fe, Cr)2O4粉体是陶瓷装饰领域很有前途的颜料。在这项工作中，以蔗糖为燃料，采用燃烧法成功合成了纳米晶 ZnFe2-xCrxO4 (x = 0, 0.2, 0.4, 0.6, 0.8, 1.0, 1.2, 1.4, 1.6, 1.8, 2.0)。TG-DTA、XRD、HRTEM、EDS、XRF、FT-IR 和光学技术被用来表征样品。所制备的 ZnFe2-xCrxO4 纳米微晶对应于纯尖晶石相，随着 Cr 含量的增加，晶格参数和微晶尺寸减小。样品的红棕色调随着 x 的增加先增加然后减少。当 x = 0.8 时，样本拥有最强的红棕色调，L* = 41.5，a* = 22.3，b* = 20.2。研究表明，ZnFe2-xCrxO4纳米微晶在增加油墨的
