Abstract
Active or functional materials such as adsorbents, catalysts, defoamers and the like are combined with inert low density particles, preferably hollow microspheres, to provide a functional material of controlled density. This product is introduced into a liquid with a somewhat higher density under agitation for a time sufficient to accomplish the desired function. Then agitation is stopped and the spent product floats to provide easy separation.
