A holmium molybdate ceramic pigment with 'allochroic effect' was prepared via mechanical activation-assisted solid-state reaction. The effects of mechanical activation mode and time as well as sintering temperature on the properties of synthesized holmium molybdate pigment were investigated by laser particle size analysis, simultaneous thermal analysis, X-ray diffraction and scanning electron microscopy, respectively. The color properties and allochroic effect of the synthesized pigments were evaluated by ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis) and colorimetry. In addition, the high-temperature stability and chemical stability of the pigments were also investigated. The results show that a sole phase of holmium molybdate can be obtained from mixed precursors ground at 1 h and sintered at 900 ℃ for 3 h, and the sintering temperature is reduced by 100 ℃, compared to that from each precursor ground separately for 2 h and then mixed or the mixed precursors unground. This is because mechanical activation pretreatment can effectively reduce the size and crystallinity of mixed precursor particles and enhance its solid-phase reaction activity, thus leading to the decrease of solid-phase reaction temperature. In addition, the pigment obtained from mixed precursors ground for 2 h has better color performance and allochroic effect under different illuminants. It is indicated that the allochroic effect of holmium molybdate pigment occurs due to the rich energy level structure of holmium ions in the visible range and the difference between relative spectral power distributions under different light sources. Meanwhile, holmium molybdate pigment can be used as a potential functional pigment in ceramic decoration and other related fields due to its high-temperature stability and chemical stability.

采用机械激活辅助固相法合成了一种具有随光异色功能的钼酸钬陶瓷色料。利用激光粒度仪、同步热分析仪、X射线衍射仪和扫描电子显微镜探究了前驱体激活方式/时间以及固相烧结温度对所合成钼酸钬产品性质的影响。采用紫外可见分光光度计和色度仪分析了色料的颜色和变色性能。此外,还考察了色料的高温及化学稳定性。结果表明,前驱体混合粉料经激活预处理1h在900 ℃烧结3 h可获得单相钼酸钬,相比未经激活的前驱体混合粉料以及先磨后混的前驱体粉料经烧结所获得单相钼酸钬所需温度降低了100 ℃,这归因于激活预处理可有效降低前驱体混合粉料中颗粒的粒径和晶体的结晶度,提高其固相反应活性,从而降低固相合成温度。另外,在不同的光照条件下,经激活预处理2 h的前驱体混合粉料在900 ℃烧结3 h后所获得的色料呈现更好的变色效果。色料的变色机理是由钬离子在可见光范围内具有丰富的能级结构和不同光源的相对光谱功率分布差异所致。同时,这种色料还具有良好的高温及化学稳定性,可作为一种潜在的功能性色料应用于陶瓷装饰等领域。

采用机械激活辅助固相法合成了一种具有随光异色功能的钼酸钬陶瓷色料。利用激光粒度仪、同步热分析仪、X射线衍射仪和扫描电子显微镜探究了前驱体激活方式/时间以及固相烧结温度对所合成钼酸钬产品性质的影响。采用紫外可见分光光度计和色度仪分析了色料的颜色和变色性能。此外,还考察了色料的高温及化学稳定性。结果表明,前驱体混合粉料经激活预处理1h在900 ℃烧结3 h可获得单相钼酸钬,相比未经激活的前驱体混合粉料以及先磨后混的前驱体粉料经烧结所获得单相钼酸钬所需温度降低了100 ℃,这归因于激活预处理可有效降低前驱体混合粉料中颗粒的粒径和晶体的结晶度,提高其固相反应活性,从而降低固相合成温度。另外,在不同的光照条件下,经激活预处理2 h的前驱体混合粉料在900 ℃烧结3 h后所获得的色料呈现更好的变色效果。色料的变色机理是由钬离子在可见光范围内具有丰富的能级结构和不同光源的相对光谱功率分布差异所致。同时,这种色料还具有良好的高温及化学稳定性,可作为一种潜在的功能性色料应用于陶瓷装饰等领域。

A holmium molybdate ceramic pigment with 'allochroic effect' was prepared via mechanical activation-assisted solid-state reaction. The effects of mechanical activation mode and time as well as sintering temperature on the properties of synthesized holmium molybdate pigment were investigated by laser particle size analysis, simultaneous thermal analysis, X-ray diffraction and scanning electron microscopy, respectively. The color properties and allochroic effect of the synthesized pigments were evaluated by ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis) and colorimetry. In addition, the high-temperature stability and chemical stability of the pigments were also investigated. The results show that a sole phase of holmium molybdate can be obtained from mixed precursors ground at 1 h and sintered at 900 ℃ for 3 h, and the sintering temperature is reduced by 100 ℃, compared to that from each precursor ground separately for 2 h and then mixed or the mixed precursors unground. This is because mechanical activation pretreatment can effectively reduce the size and crystallinity of mixed precursor particles and enhance its solid-phase reaction activity, thus leading to the decrease of solid-phase reaction temperature. In addition, the pigment obtained from mixed precursors ground for 2 h has better color performance and allochroic effect under different illuminants. It is indicated that the allochroic effect of holmium molybdate pigment occurs due to the rich energy level structure of holmium ions in the visible range and the difference between relative spectral power distributions under different light sources. Meanwhile, holmium molybdate pigment can be used as a potential functional pigment in ceramic decoration and other related fields due to its high-temperature stability and chemical stability.
