From the SEM observations, it follows that after sols composition and processing parameters optimization, sols can be deposited on cotton fibres in the form of thin xerogel coats, which completely and uniformly cover the fibre surface, with no cracks or fractures and therefore should positively influence their resistance, as is clearly seen in the SEM images.

Overall, there are few reports on silica xerogel preparation from coal gangue, the reported utilization of the silicon resource was lower than 70%, and no systematical characterizations of such materials, but quite a lot of publications, were reported for precipitated silica fabrications [20-22]; however, the main challenge of aerogel preparation is controlling high Si[O.
