发明名称 Method of producing ceramic composition and method of producing electronic device
摘要 A method of producing an electronic device comprising a dielectric layer constituted by 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 mole ratio m satisfies 0.94<m<1.08, the code x satisfies 0≤x≤1.00 and the code y satisfies 0≤y≤0.20; and a fourth subcomponent including an oxide of R (note that R is at least one of rare-earth element); characterized by producing the dielectric ceramic composition by using a composition source material wherein at least a part of a source material for the fourth subcomponent is brought to react with a source material for the main component. According 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 an accelerating lifetime of insulation resistance is improved and thus the credibility is improved. <IMAGE>
