Abstract
Positron annihilation method has been used fox investigating amorphous nonporous pyrogeneous silica of high purity. The influence of water a dsorption 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.
