Paper Title:
Study on Nano SiO2 Synthesized by Gaseous Detonation under Different Initial Temperature
  Abstract

Taking the mixed gas of the silicon tetrachloride, the air and the hydrogen as the explosion source, adjusting the initial temperature of the mixed gas and detonating it in the gaseous detonation tube, after washing, filtering with alcohol and drying, the nanometer SiO2 powder is obtained. The analysis on the nanometer SiO2 powder is carried on with X-ray fluorescence spectroscopy, transmission electron microscopy and x-ray diffraction instrument. By analyze the ingredient of the obtained product with x-ray fluorescence spectrometry, it is measured that its main component is SiO2; by XRD analysis, it is known that the generated SiO2 belongs to the typical amorphous structure; by TEM images, it can be seen that particle size are mostly between 20~30nm, the particle shape is spherical, also the dispersion is good. Under the conditions of the initial temperature 140°C, the product particle size is finer, and the dispersion is better.
