| Abstract: | Silica aerogels were made by the sol gel process followed by means of supercritical drying. The structure and composition changes of aerogels were investigated by using thermal analysis, Fourier transmission infrared spectroscopy and X ray diffraction. The influence of heat treatment on the morphology of aerogels was observed by scanning electron microscopy. |
