    Abstract: Intimate dispersions of particulate aluminosilicates and refractory oxides are prepared in aqueous media in the presence of an oxygen containing amine followed by separation and drying of the resultant dispersion. The original aluminosilicate or refractory oxide can contain active components, stabilizing compositions and the like, as such or in a form that can be subsequently converted to such active components by thermal or chemical treatment. Similarly the dispersion of the aluminosilicate in the refractory oxide can be combined with catalytically active, stabilizing or otherwise chemically or physically modifying compositions.
