Abstract: | Positron annihilation method has been used for investigating amorphous nonporous pyrogeneous silica of high purity. The influence of water adsorption on the structure of the silanol surface is shown. The effect of swelling, that is an increase of interglobular free volume at intermediate degrees of silica hydration has been observed. |
