ABSTRACT:
The invention relates to gels produced by dispersing solid primary particles of an inorganic substance in a liquid to form a sol containing colloidal particles which are aggregates of the primary particles and drying the sol to produce a porous gel.
The gels find applications in chromatography. Calcined gels give porous ceramic materials suitable for use as catalyst supports.
