  • 本研究利用(BaCa)(TiZr)O3為主要材料,以MLCC BME產品製程來製備其樣本,並利用疊壓技術將以X7R為抑制層的生胚薄片,疊壓在BCTZ的樣品上,使其燒結時,來抑制BCTZ的收縮。
    此外,引用快速燒結的方式,使其在燒結過程中更能有效抑制內電極層的收縮,來得到更佳的內電極連續性。
    實驗結果發現,將抑制層加入於MLCC的結構中,能有效的抑制其BCTZ在X&Y方向的收縮,且晶粒大小也同時被抑制住。而導入快速燒結的方式更能獲得更佳的內電極連續性,且同時給予較短的燒結時間也能有控制晶粒大小的效果。

    Based on BCTZ by MLCC BME process, to add constraint layers inside on the samples to control the shrinkage.
    Besides, apply rapid sintering concept to resist inner electrode shrinkage during sintering. Depending on this concept, expect to get good continuity of inner electrode.
    According to results, constraint layers added can be useful to control grain growth of BCTZ. At the same time, rapid sintering performs good continuity of inner electrode and repression of grain growth.
