Abstract
There is produced crystalline zeolite powder of Type A having an average particle diameter of 8.5 to 9.0.mu. by introducing the components waterglass and alkali aluminate liquor under defined conditions simultaneously into a receiver containing alkali aluminate, stirring, first adding more alkali aluminate liquor and then more waterglass solution. The thus obtained crystalline zeolite powder of Type A is used as a phosphate substitute in washing agents.
