Method of producing ceramic composition and method of producing electronic device |
| 摘要 |
A method of producing an electronic device comprising a dielectric layer includes a dielectric ceramic composition containing a main component expressed by a composition formula of ä(Sr1-x Cax)Oüm • (Ti1-y Zry)O2, wherein the code x in said ccmposition formula fulfills 0≤x≤1.00 and the code y in said composition formula fulfills 0≤y≤0.20, and characterized by producing said dielectric ceramic composition by using a material expressed by a composition formula of ä (Sr1-x Cax)Oüm' • (Ti1-y Zry)O2 wherein the mole ratio m' in said composition formula fulfills m'<m. Due to the method, it is possible to produce an electronic device, such as a chip capacitor, having excellent resistance to reducing during firing and excellent capacity-temperature characteristics after firing, wherein the insulation resistance does not deteriorate easily. <IMAGE> |
