ABSTRACT:
The present invention relates to materials and more particularly to composite materials in which a selected substance is supported by a support material.
A composite material in accordance with the present invention comprises porous hollow particles of an inorganic material in which there is supported a selected substance (such as chromagraphic organic gel, or a liquid for use in two-phase separation processes).
The porous hollow particles may be formed from, for example, a material such as kieselguhr and/or an inorganic oxide.
The porous hollow particles may be formed by coating a fugitive core material (e.g. organic beads) with inorganic material and heating to remove the fugitive core material.
