Abstract
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.
Claims5
A rectifier comprising:
- a titanium dioxide main body with a fine-grain, porous, polycrystalline structure and having a pair of opposing major surfaces;
- a pair of spaced platinum electrodes on said titanium dioxide main body disposed on said opposing major surfaces of said main body;
- and
- groupings of PtTi.sub.3 interspersed throughout said titanium dioxide main body thereby forming a rectifier with electrodes of one material and having different forward and reverse electrical characeristics so that rectification is derived from a microstructure, including said groupings, of said main body.

A rectifier comprising:
- a fine grain, porous, polycrystalline, titanium dioxide main body having a pair of opposing major surfaces;
- a pair of spaced platinum electrodes on said titanium dioxide main body disposed on said opposing major surfaces of said main body;
- groupings of PtTi.sub.3 interspersed throughout said titanium main body so that said rectifier has a maximum forward resistance at one volt of approximately 5,000 ohms and a minimum backward resistance at 1 volt of approximately 100,000 ohms so that rectification is derived from the microstructure of said main body.
A rectifier comprising:
- a ceramic oxide main body having a pair of opposing major surfaces, said ceramic oxide being an oxide of a tetravalent metal atom;
- a pair of spaced metal electrodes disposed on said opposing major surfaces of said ceramic oxide main body, the material of said metal electrodes being selected from the group of platinum and palladium;
- and
- groupings of a combination of the electrode material and the tetravalent metal material interspersed throughout the ceramic oxide main body thereby forming a rectifier with electrodes of one material and having different forward and reverse electrical characteristics so that rectification is derived from a microstructure, including said groupings, of said main body.
