Abstract: The compaction density and thermal conductivity of granular, fused magnesia used as thermally conducting electrical insulation in tubular, electrical resistance elements is substantially improved by controlled surface hydroxylation of the magnesia powder before compacting it in a heating element in the usual manner.

Abstract: Both the passivation of aluminum foil particularly for use as electrodes in wet electrolytic capacitors and the inhibition of the aluminum-water reaction within the completed capacitor are described. Pretreatment of etched aluminum foil includes the combined steps of immersion in a boiling aqueous solution containing Cr03 and H3PO4 followed by a 3-minute immersion in a boiling solution of controlled pH containing H2PO4 , SiO3 and CrO3. Inhibition of aluminum in a wet electrolytic capacitor is afforded by the addition of a concentration of at least one of the following inhibiting ions to the liquid electrolyte: phosphate, phosphite, periodate, arsenate, tungstate, silicate, vandadate, tellurate, tellurite, antimonate, arsenite, selenate, sulfite and germanate.
