METHOD OF PRODUCING RECTIFIER

摘要

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 DEG -850 DEG 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.
