Ta and Al co-doped strontium titanate-based giant dielectric ceramic material and preparation method thereof
The invention relates to the technical field of electronic functional materials, and provides a Ta and Al co-doped SrTiO3-based giant dielectric ceramic material and a preparation method thereof. According to the Ta and Al co-doped SrTiO3-based giant dielectric ceramic material, Ta and Al are used for co-doping SrTiO3, the dielectric constant of the obtained Ta and Al co-doped SrTiO3-based giant dielectric ceramic material is 105 magnitude, the frequency and temperature stability of the dielectric constant is good, and the requirements of miniaturization of electronic components and energy storage devices for dielectric materials can be met. Moreover, when the Ta and Al co-doped SrTiO3-based giant dielectric ceramic material is prepared, a hydrogen atmosphere does not need to be adopted, only sintering is carried out under a nitrogen condition, the safety is good, the cost is low, and large-scale production is easy to carry out.
本发明涉及电子功能材料技术领域，提供了一种Ta、Al共掺杂SrTiO3基巨介电陶瓷材料及其制备方法。本发明利用Ta、Al对SrTiO3进行共掺杂，所得Ta、Al共掺杂SrTiO3基巨介电陶瓷材料的介电常数在105量级，且介电常数的频率、温度稳定性良好，能够满足电子元器件小型化和储能器件对电介质材料的需求。并且，本发明在制备Ta、Al共掺杂SrTiO3基巨介电陶瓷材料时，无需采用氢气气氛，仅在氮气条件下烧结即可，安全性好，成本低，容易进行大规模生产。
