摘要

通过对烧结-溶解过程中固结的多孔镍（II）进行循环氧化还原后处理，制备了具有纳米结构表面和多级分级孔隙率的可渗透镍金属和氧化镍陶瓷材料。颗粒内孔隙率的附加水平——Kirkendall孔和收缩纳米孔——分别在空气中的高温氧化和氢气中的还原阶段形成。

Redox Nanostructuring of Biporous Nickel(II) Sintered Using a Space Holder

Permeable nickel metallic and nickel oxide ceramic materials with nanostructured surface and multilevel hierarchical porosity were created by cyclic redox post-treatment of biporous nickel(II) consolidated in the sintering–dissolution process. Additional levels of intraparticle porosity—Kirkendall pores and shrinkage nanopores—were formed during the stages of high-temperature oxidation in air and reduction in hydrogen, respectively.
