Sasol markets a wide range of doped materials. Silica doped materials are sold worldwide under the trade names SIRAL® and SIRALOX® for their silica-alumina hydrates and oxides respectively.

The know-how gained from the production of high purity alumina products has been carried over to our range of doped materials so that the quality of the products is uncompromised and manufactured to the same high standards. The use of dopants affects the physical properties of alumina in many ways. SIRAL® and SIRALOX® are not only more thermal stable than high purity aluminas but they are also more acidic.

Both the hydrate and the oxide are suitable carriers for catalytic processes where surface acidity is required to enhance catalytic activity.
