Lanthanum-hafnium co-doped silver niobate-based anti-ferroelectric ceramic material and preparation method thereof
The invention relates to the technical field of functional ceramic materials, and discloses a lanthanum-hafnium co-doped silver niobate-based anti-ferroelectric ceramic material and a preparation method thereof. The chemical formula of the lanthanum and hafnium co-doped silver niobate-based anti-ferroelectric ceramic material is (Ag1-3xLax) (Nb1-0.8 yHfy) O3, x is more than 0 and less than or equal to 0.08, and y is more than or equal to 0.001 and less than or equal to 0.005. The lanthanum and hafnium co-doped silver niobate-based anti-ferroelectric ceramic material is prepared by taking Ag2O, Nb2O5, La2O3 and HfO2 as raw materials through a tape casting process. The lanthanum-hafnium co-doped silver niobate-based anti-ferroelectric ceramic material prepared by the invention does not contain heavy metals such as lead, and is an environment-friendly pulse energy storage material; moreover, the releasable energy storage density reaches 8.28 J/cm < 3 >, the energy storage efficiency reaches 73%, and the material has excellent energy storage performance.
本发明涉及功能陶瓷材料技术领域，公开了一种镧铪共掺的铌酸银基反铁电陶瓷材料及其制备方法。本发明镧铪共掺的铌酸银基反铁电陶瓷材料，化学式为(Ag1‑3xLax)(Nb1‑0.8yHfy)O3，其中0＜x≤0.08，0.001≤y≤0.005。本发明以Ag2O、Nb2O5、La2O3和HfO2为原料经流延工艺制备得到了镧铪共掺的铌酸银基反铁电陶瓷材料。本发明制备得到的镧铪共掺的铌酸银基反铁电陶瓷材料不含铅等重金属，是一种环保型脉冲储能材料；而且，其可释放储能密度达8.28J/cm3，储能效率达73％，具有优异的储能性能。
