Multi-main-component dopant for zirconium oxide
The invention relates to a multi-main-component dopant for zirconium oxide, and belongs to the field of materials. A mixture of various rare earth oxides and transition metal oxides is adopted as a multi-main-component doping agent, tetragonal-phase/cubic-phase doped zirconium oxide is obtained through solid-phase sintering, and the tetragonal-phase/cubic-phase doped zirconium oxide has more excellent fracture toughness, high-temperature stability and ideal oxygen ion conductivity; the molar ratio of the dopant to the zirconium oxide is x: 100-x, wherein x is more than or equal to 5 and less than or equal to 15. Compared with the prior art, the multi-main-component doped zirconium oxide has the advantages that the performance is excellent, the addition amount of each component dopant in the multi-main-component doped zirconium oxide is basically fixed, and the difficulty of optimizing/regulating the comprehensive performance of the doped zirconium oxide due to the diversity of the addition amount is avoided.
本发明涉及一种用于氧化锆的多主组元掺杂剂，属于材料领域。本发明采用多种稀土氧化物和过渡金属氧化物的混合物作为多主组元掺杂剂，通过固相烧结获得四方相/立方相掺杂氧化锆，具有更为优异的断裂韧性、高温稳定性和理想的氧离子电导率；所述掺杂剂和氧化锆的摩尔比为x：100‑x，其中x满足：5≤x≤15。相比于此前传统技术，本发明不但性能优异，而且多主组元掺杂氧化锆中各组元掺杂剂彼此间添加量基本固定，避免了添加量多样性给优化/调控掺杂氧化锆综合性能所带来的困难。
