通过五水硝酸铋水解法制备微米花状结构氯氧化铋(BiOCl)晶体。探究反应温度、时间和表面活性剂十六烷基三甲基溴化铵(CTAB)对BiOCl晶体形貌的影响,利用XRD、FE-SEM、FT-IR和TGA等表征方法对BiOCl晶体进行特征分析。结果表明,在CTAB表面活性剂的作用下,水解温度为90℃,水解反应2h可以得到微米花状BiOCl晶体,并具有良好的珠光性能。通过对所制备的BiOCl晶体进行吸油量测定,该微米花状BiOCl珠光颜料的表面亲油效果良好。
The flower-like microstructure bismuth oxychloride crystal was prepared by the hydrolysis of bismuth nitrate pentahydrate.The influences of reaction temperature,time and cetyltrimethyl ammonium bromide (CTAB) surfactant on BiOCl crystal morphology were investigated,the characterization of BiOCl crystal was characterized by XRD,FE-SEM,FT-IR and TGA.The results showed that under the action of CTAB surfactant the flower-like microstructure BiOCl crystal with good pearlescent performance can be obtained when the hydrolysis temperature was 90℃ and hydrolysis reaction for 2h.The surface lipophilic effect of BiOCl was good by measuring the oil absorption of BiOCl crystal.
