隨著科技的進步，積層陶瓷電容已成為被廣泛使用的被動元件。然而，目前的積層陶瓷電容仍面臨一些問題，包括貴金屬電極成本過高以及卑金屬電極製程需要特殊環境，且容易出現半導化現象。
本研究採用混合不同比例的銅、鎳和鋁作為積層陶瓷電容的內電極，並透過多段燒結和形成鋁銅鎳合金的方式，提高在空氣中燒結的抗氧化性。初步結果顯示，在1100℃下燒結30分鐘後，使用此新穎方式製備的內電極仍保持良好的導電性。這種方法不僅可以降低材料成本，同時也降低了製作成本。未來，我們計劃延長燒結時間，以進一步開發低成本高規格的積層陶瓷電容。
這項研究成果有望為積層陶瓷電容的製造提供一個具有潛力的解決方案。透過開發能夠在空氣中燒結的卑金屬內電極，不僅可以滿足不斷增長的市場需求，還可以促進先進技術的發展，如智慧型手機、電動車和5G通訊等。此外，這項研究還為未來降低成本且具有高性能的積層陶瓷電容的開發提供了一個有前景的方向。

With the advancement of technology, multilayer ceramic capacitor (MLCC) have become widely used passive components. However, current MLCC still face some challenges, including the high cost of noble metal electrodes and the requirement for special environments in the fabrication process of base metal electrodes, which are prone to semiconductive phenomena.
In this study, a mixture of copper, nickel, and aluminum in different proportions was used as the internal electrode for MLCC. Through multi-stage sintering and the formation of aluminum-copper-nickel alloys, the oxidation resistance during air sintering was improved. Preliminary results showed that the internal electrodes fabricated using this novel method maintained good conductivity after sintering at 1100℃ for 30 minutes. This approach not only reduces material costs but also lowers production costs. In the future, we plan to extend the sintering time to further develop low-cost, high-performance MLCC.
The findings of this study are expected to provide a promising solution for the manufacturing of MLCC. By developing base metal internal electrodes that can be sintered in air, we can meet the growing market demand and promote the advancement of advanced technologies such as smartphones, electric vehicles, and 5G communications. Additionally, this research provides a prospective direction for the future development of cost-effective and high-performance MLCC.
