This specification discloses a titanium dioxide rectifier element. A pair of spaced platinum electrodes are on a titanium dioxide main body. Groupings of PtTi.sub.3 are interspersed throughout the titanium dioxide main body thereby forming a rectifier with electrodes of one material and having a different forward and reverse electrical characteristics.

Titanium dioxide rectifier

This specification discloses a method of fabricating a titanium rectifier circuit element. A titanium dioxide main body is formed with a pair of spaced faces each of which having thereon a platinum electrode. A dc voltage is applied across this structure, heating the structure to a temperature of about 750.degree.-850.degree. C. In this temperature range, the titanium dioxide body is subjected to a cyclic sequence of exposures to oxidizing and reducing atmospheres. The final step includes cooling down the titanium dioxide body in the presence of a reducing atmosphere with an applied dc electric field.
