ABSTRACT:
Sponge titanium powder is compacted, advantageously by roll compaction to a density in the range of about 60% to 80% of the density of solid titanium metal, thereafter heat treated in vacuum at about 500.degree. C. to 750.degree. C., cooled in vacuum to 300.degree. C. and quenched to 100.degree. C. to provide a substrate for electrodes useful in electrolytic processes.
