Abstract
Layered silicate materials of high thermal stability and surface area which contain interspathic oxides such as silica as prepared by treating a layered silicate, with organic cation, to spread the layers apart. A compound such as tetraethylorthosilicate, capable of forming said oxide, is thereafter introduced between the layers. The resulting product is treated to form the oxide, e.g. by hydrolysis, to produce the layered silicate material. The resulting product may be employed as a catalyst material in the conversion of hydrocarbons.
