KLATRASIL AV STRUCTURAL DODEKASIL 1 H MED LITEN MEDELKRISTALLSTORLEK

摘要

The invention relates to a process for preparing crystalline clathrasil of the dodecasil 1 H structure type having a mean crystal size of no more than 20 mu m, characterised in that an alkaline aqueous silicate-containing medium which contains templates and crystallisation nuclei is tempered, the crystallisation nuclei content based on the SiO2 content of the medium being not less than 1% by weight.
