Copper inner electrode MLCC and sintering method thereof
The invention belongs to the field of multi-layer chip ceramic capacitor (MLCC) preparation, and particularly relates to a copper inner electrode MLCC and a sintering method thereof. According to the method, modification is carried out by controlling ceramic components, so that good reduction resistance of the MLCC is achieved, the powder pile height is regulated and controlled in combination with buried powder sintering treatment, the sintering atmosphere and flow are controlled, good sintering consistency is achieved, a ceramic body is compact, grain growth is uniform, and good sintering consistency and high-frequency low-loss performance of the copper inner electrode MLCC are achieved.
本发明属于多层片式陶瓷电容器(MLCC)制备领域，具体涉及一种铜内电极MLCC及其烧结方法。本发明通过控制陶瓷组分进行改性实现MLCC良好的抗还原性，并且结合埋粉烧结处理调控粉堆高度、控制烧结气氛、流量，实现良好的烧结一致性，瓷体致密，晶粒生长均匀，实现铜内电极MLCC良好的烧结一致性及高频低损耗性能。
