Abstract

A method for the manufacture of crystallite particles, said method comprising the steps of: a) reacting a reaction solution comprising a silicate, a micelle forming agent, an alkane, a salt under stirring at pH 2 or lower, wherein the reaction solution comprises HCI in a concentration of at least 1.5 M, wherein the stirring is performed not more than 10 minutes, and b) treating the obtained material to remove the micelle forming agent with one method selected from i) heat treating the material above 300° C., ii) treating the material with at least one selected from H2O2, and H2SO4, iii) treating the material with microwaves to digest the micelle forming agent. An advantage is that the time for the synthesis is shortened considerably compared to the prior art.
