Claims
- 1. A method of producing a monolithic ceramic capacitor comprising the steps of:providing at least two titanate ceramic green sheets each of which comprises titanate and Li2O—(TiO2.SiO2)—Al2O3 oxide glass and has an electrode including a base metal M on a surface of said sheet, wherein said base metal M has an equilibrium oxygen partial pressure of oxide MO at the maximum temperature which will be achieved during firing; laminating at least two of said green sheets to form a laminated body having the electrode on one of the sheets disposed so as to form an inner electrode; firing said laminated body at an oxygen partial pressure of about said equilibrium oxygen partial pressure so as to form a layer comprising Si oxide adjacent to the inner electrode; and electronically connecting said inner electrode to an outer electrode on an outer surface of said laminated body.
- 2. A method of producing a monolithic ceramic capacitor according to claim 1, wherein said base metal is nickel or nickel alloy.
- 3. A method of producing a monolithic ceramic capacitor according to claim 1, wherein said titanite ceramic green sheet comprises barium titanate, magnesium oxide, and said Li2O—(TiO2.SiO2)—Al2O3 glass.
- 4. A method of producing a monolithic ceramic capacitor according to claim 1, wherein said titanate ceramic green sheet comprises barium titanate, magnesium oxide and silicon oxide.
- 5. A method of producing a monolithic ceramic capacitor according to claim 1, wherein said laminated body contains silicon prior to firing.
- 6. A method of producing a monolithic ceramic capacitor according to claim 5, wherein the silicon is a constituent of the titanate ceramic green sheet.
- 7. A method of producing a monolithic ceramic capacitor according to claim 5, wherein the silicon is a component of a material used to make said inner electrode.
- 8. A method of producing a monolithic ceramic capacitor consisting essentially of the steps of:providing at least two titanate ceramic green sheets each of which comprises titanate and Li2O—(TiO2.SiO2)—Al2O3 oxide glass and has an electrode including a base metal M on a surface of said sheet, wherein said base metal M has an equilibrium oxygen partial pressure of oxide MO at tie maximum temperature which will be achieved during firing; laminating at least two of said green sheets to form a laminated body having the electrode on one of the sheets disposed so as to form an inner electrode; firing said laminated body at an oxygen partial pressure of about said equilibrium oxygen partial pressure so as to form a layer comprising Si oxide adjacent to the inner electrode; and; and electronically connecting said inner electrode to an outer electrodes on an outer surface of said laminated body.
