摘要： The invention relates to a method for producing zeolite particles having an average particle size of less than 1000 nm, whereby a) a solution is produced from a silicate source, and/or a germanate source and a base, b) a solution is produced from an aluminate source and/or a gallate source and a base, and c) the solutions (a) and (b) are combined, mixed and reacted. The inventive method is characterised in that the pH value of the solution in step (a) is at least 11, and the pH value of the solution in step (b) is at least 11. The invention also relates to nanoscale zeolite particles which can be obtained by the inventive method, and colloidal suspensions containing nanoscale zeolite particles.
