摘要

二氧化硅以其优越的耐热隔热性能引起各个行业的广泛关注。以硅酸钠为硅源、氯化铵为沉淀剂、十六烷基三甲基溴化铵（CTAB）为分散剂，采用化学沉淀法合成二氧化硅纳米颗粒。采用TG-DSC测试分散剂CTAB的分解温度，并用傅里叶红外光谱、X射线以及扫描电镜对制备的二氧化硅粉末进行表征。结果表明，此方法制备的二氧化硅颗粒为无定形态纳米颗粒，平均粒径为80 nm。

Abstract

With excellent physical characteristics such as heat proof

thermal insulation and abrasion resistance

etc.

silica nanoparticles have attracted a lot interesting from various industries. Many methods have been proposed to formulate SiO2 nanoparticles

for example

aerosol method

chemical precipitation method

microemulsion method and sol-gel method. Compared with other methods

chemical precipitation uses cheaper materials and is easily to be industrialized. In present work

based on the chemical precipitation method

SiO2 nanoparticles were prepared using sodium silicate (Na2SiO3) as silicon source

ammonium chloride (NH4Cl) as precipitant and cetyl trimethyl ammonium bromide (CTAB) as dispersant. TG-DSC was used to determine the decomposition temperature of CTAB. After the preparation

SiO2 nanoparticles were characterized using Fourier Transform Infrared Spectrometer (FTIR Spectrometer)

X-Ray Diffraction (XRD) and Scanning Electron Microscope (SEM). Results show that SiO2 nanoparticles formulated by chemical precipitation were amorphous state with an average diameter of 80 nm.
