Abstract
Synthetic Amorphous Silica (SAS) is produced and marketed since the early 1940’s and can be regarded as a nanostructured material since the first production even though the term ‘nano’ was not defined back then, and early publications describe the structure often as ‘milli-micron’. The present paper of Evonik Industries AG reviews the history of innovation and production of this “seasoned”, but evergreen product.
