一种Sm、Al共掺杂取代Nd1.9Sr0.1NiO4巨介电陶瓷及其制备方法
摘要：
本发明公开了一种Sm、Al共掺杂取代Nd1.9Sr0.1NiO4巨介电陶瓷及其制备方法。由Sm取代一部分Nd由Al取代一部分Ni以化学通式Nd1.9-xSmxSr0.1Ni1.0-yAlyO4表示，其中，x＝0.05～0.2，y＝0.05～0.2。本发明提供的Sm、Al共掺杂取代Nd1.9Sr0.1NiO4巨介电陶瓷材料有效地提高了产品的介电性能，制备方法简单和重复性好，且不需要额外的气氛辅助烧结。
摘要（英）：

The invention discloses an Sm and Al co-doped substituted Nd1.9Sr0.1NiO4 gigantic dielectric ceramic and a preparation method thereof. The Sm and Al co-doped substituted Nd1.9Sr0.1NiO4 gigantic dielectric ceramic is characterized in that Sm substitutes part of Nd, and Al substitutes part of Ni, and then the chemical formula Nd1.9*xSmxSr0.1Ni1.0-yAlyO4 is adopted, wherein x is 0.05 to 0.2; y is 0.05 to 0.2. According to the Sm and Al co-doped substituted Nd1.9Sr0.1NiO4 gigantic dielectric ceramic, Sm and Al are co-doped to substitute Nd1.9Sr0.1NiO4 gigantic dielectric material, thus the dielectric performance of the product is effectively improved; the preparation method is simple, and high in repeatability; moreover, additional atmosphere supporting sintering is avoided.
