技术领域
本发明提供一种具有纳米孔结构的氧化铪粉体的制备方法,属于纳米粉体材料领域。
背景技术
目前,氧化铪材料已被用于快离子导体燃料电池、氧传感器、红外窗口保护膜、原子反应堆的控制棒、催化剂等领域。其中HfO2溅射薄膜由于具有高介电常数、高介电强度、低介电损耗、低漏电流及良好的电容-电压特性、良好的稳定性以及能与基体硅的牢固结合等优点,被认为是最有前途的新型绝缘介质膜之一。二氧化铪用作催化剂时,若赋予其发达的孔隙结构不仅有利于电荷在相间的传递,改善其电荷传导性能,同时,也可以减小反应物分子或产物分子在催化剂中的扩散阻力,改善其催化反应性能。但常规的二氧化铪热稳定性差、比表面小、孔隙欠发达,孔径大小变化无规律等,限制了其优良性能的发挥。
