Ni電極積層セラミックコンデンサの容量エージングに及ぼす 結晶異方性の影響 Effect of Tetragonality on The Capacitance Aging of Multilayer Ceramic Capacitors with Ni Internal Electrodes 三浦, 純子 川野, 直樹 嵐, 友宏 MIURA, Junko KAWANO, Naoki ARASHI, Tomohiro open access Capacitance aging Relaxation Tetragonality Internal stress Nielectrode MLCCs BaTi03 Effect of tetragonality on the capacitance aging under dc field has been studied. BaTi03 -based dielectrics with X7R characteristics and Y5V characteristics for multilayer ceramic capacitors (MLCCs) with Ni internal electrodes have been used for this study. Capacitance change strongly depends on grain size and temperature. It is supported that these factors affect tetragonality, and the change of tetragonality causes variation of capacitance change. New equation for capacitance aging is proposed considering the effect of particle volume, temperature, dc electric field and tetragonality. Effect of internal stress of MLCCs is also discussed. Capacitance change is also a function of internal stress. 日本素材物性学会 1997-08-01 jpn journal article VoR http://hdl.handle.net/10295/1215 https://air.repo.nii.ac.jp/records/1268 09199853 AN10140273 素材物性学雑誌 10 1 70 78 https://air.repo.nii.ac.jp/record/1268/files/sozai10a8.pdf application/pdf 715.9 kB 2017-02-16
