摘要
采用低温燃烧合成法和共沉淀法分别制备了Ba2+掺杂γ-Ce2S3色料的前驱体.系统研究了不同制备方法对γ-Ce2S3色料前驱体的物相组成、孔径、微观形貌及γ-Ce2S3硫化温度和粒度的影响.结果表明,与共沉淀法相比,采用低温燃烧合成法制备的前驱体具有三维网络多孔结构,前驱体颗粒粒径更细,表现出较高的比表面积(27.05 m2/g);同时,低温燃烧合成法制备的γ-Ce2S3色料前驱体的硫化温度从900℃降至850℃,得到的色料颗粒平均粒径从14.07μm降至3.89μm.低温燃烧合成法制备的γ-Ce2S3色料在保持a*值稳定的情况下,其b*和L*值比共沉淀法制备的色料更高,色料整体呈色更明亮.
Abstract
In this work,the precursor of Ba2+doped γ-Ce2S3 pigments was prepared by low-temperature combustion synthesis (LCS) and the co-precipitation method,respectively. The effects of different preparation methods on the phase composition,pore size,micromorphology of the γ-Ce2S3 pigment precursors,sulfuration temperature and particle size of the pigment obtained were systematically studied. The results show that the ultrafine precursor particles synthesized via LCS possess a three-dimensional network porous structure,demonstrating a higher specific surface area (27.05 m2/g) compared to the co-precipitation method. Additionally,the sulfuration temperature for the γ-Ce2S3 pigment precursors prepared by LCS was reduced from 900℃ to 850℃,resulting in an average particle size of the pigment obtained decreasing from 14.07 μm to 3.89 μm. Under the condition of maintaining a stable value a*,the values b* and L* of γ-Ce2S3 prepared by the LCS method are higher than those prepared by co-precipitation,resulting in a brighter overall color for the pigment.
