ABSTRACT:
A process for making ceramic spheriods by mixing and converting spheroids, with the aid of water, raw materials of 50-99.8 parts by weight mineral particulate (e.g. blend of orthoclase, nepheline, hornblende and diopside) which particulate includes at least one mineral having chemically bound water or sulphur in a form which is not substantially water soluble and in amounts sufficient to yield 0.5 to 5 weight percent water or 0.04 to 2 weight percent sulphur in the total mass; 0.1 to 50 parts by weight silicon carbide; and 0.1 to 15 parts binder. The wet spheroids are dried and the dry spheroids are fired in contact with a parting agent (e.g. aluminum oxide) for a sufficiently long time to form a shell containing parting agent on the ceramic mineral having a fired density of less than about 2.9 grams per cubic centimeter when fired above 1,100.degree. C. The binder is typically bentonite clay.
