ABSTRACT:
A mixture of powdered metal oxide and thermally decomposable organic binder is formed into particles or beads of a controlled size. The beads are heated to a temperature sufficient to decompose the binder to carbon or to oxidize it completely. If desired, porosity control agents, such as starch, may also be included in the original mixture.
