Claims
- 1. A ceramic capacitor, comprising:
- a thick core formed of a sintered ceramic material; and
- a pair of electrodes formed on opposing end faces of said core, said electrodes being a reduced layer of an oxide formed on the ceramic material of the core.
- 2. The ceramic capacitor of claim 1, wherein said oxide includes an element selected from the group consisting of Zn, Pb, Bi, Sb, Vb, Sc and Ta.
- 3. The ceramic capacitor of claim 1, wherein said core is cylindrically-shaped.
- 4. The ceramic capacitor of claim 1, wherein said core is plate-shaped.
- 5. The ceramic capacitor of claim 1, wherein said core is disk-shaped.
- 6. The ceramic capacitor of claim 1, wherein the thickness of said core is substantially greater than the thickness of said reduced electrode.
- 7. The ceramic capacitor of claim 1, wherein said thick core is formed from one of the group consisting of PZT, PbZrO.sub.3, and PbTiO.sub.3.
- 8. A ceramic capacitor formed by the process of:
- (a) forming a ceramic core by sintering a prepared ceramic precursor powder;
- (b) applying an oxide layer on said ceramic core;
- (c) reducing the surface said oxide layer found on said core by performing heat treatment in reducing atmosphere; and
- (d) removing unnecessary portions of said reduced layer by machining or the like resulting in electrodes formed on opposing end faces of said core.
