A family of novel and unique synthetic alkali metal aluminosilicates (SAMS) are produced by the hydrothermal reaction between kaolin clay and alkali metal silicates. The integrated composition of the SAMS products is a unique entity having an overall composition of xM.sub.2 O:Al.sub.2 O.sub.3 :ySiO.sub.2 :zH.sub.2 O where x is the number of moles of alkali metal oxide and is an integer from 0.01 to 2.0, M is an alkali metal, y is the number of moles of SiO.sub.2 in the unique SAMS composition, and z is the number of moles of bound water and is an integer ranging from 1.0 to 5.0. The composition essentially comprises altered kaolin clay platelets with an integral rim or protuberance of essentially amorphous alkali metal silicate-kaolin reaction product. The unique SAMS compositions are structured materials in which the structure can be controlled, and are therefore useful as functional fillers, as TiO.sub.2 extenders, as silica extenders or as reinforcing agents for paper, paint, rubber, plastics and specialty products.
A catalyst composition comprising an ion exchanged alkali metal alumino-silicate composition, the alkali metal alumino-silicate having a composition in terms of mole ratio of oxides as follows:
A catalyst composition which comprises an ion exchanged, alkali metal alumino-silicate composition, said alkali metal alumino-silicate comprising a core of kaolin clay platelets which have been altered at their edges by reaction so as to be integral with one or more adjacent areas of essentially amorphous alkali metal silicate-base kaolin clay reaction product having a composition in terms of mole ratio of oxides as follows:
