摘要
在沉淀法制备纳米白炭黑的实验过程中,调整酸的质量分数、反应体系的温度、pH值、原料参数等,同时严格控制陈化时间、酸滴加速度等合成条件,优化制备工艺参数,得到粒径小、品质好的纳米白炭黑。利用X-ray衍射仪和扫描电镜分析研究了白炭黑的结构。
During the test of preparing nano-silica aerogel with small size and good quality could be got by adjusting synthesis conditions, such as concentration of acid, temperature of action system, pH value, raw material parameters etc., and optimizing process parameters. The structure of nano-silica aerogel was studied with X-ray diffraction instrument and scanning electron microscope.
