Fabrication and characterization of Cu/YSZ cermet high temperature electrolysis cathode material prepared by high-energy ball-milling method

Fabrication and characterization of 900°C-sintered Ni/Cu/YSZ cermet high temperature electrolysis cathode material prepared by high-energy ball-milling method

“…While some condensation of water vapor on Cu/YSZ cathode could also contribute to the noise, following the arguments of Gorte et al [24], acicular formation of copper crystals on Cu/YSZ cathode implies preponderance of reducing atmosphere, i.e. hydrogen, and negligible contribution of condensed water vapor to the noise [23].…”

“…The voltage variation of Cu/YSZ electrode during HTE was relatively stable and the source of the noise is attributed to the formation of acicular copper on Cu/YSZ cathode [23]. While some condensation of water vapor on Cu/YSZ cathode could also contribute to the noise, following the arguments of Gorte et al [24], acicular formation of copper crystals on Cu/YSZ cathode implies preponderance of reducing atmosphere, i.e.…”

“…The authors also tested similarly fabricated Cu/YSZ cermet cathode for HTE [23]. The voltage variation of Cu/YSZ electrode during HTE was relatively stable and the source of the noise is attributed to the formation of acicular copper on Cu/YSZ cathode [23].…”

“…Nowadays, these techniques have been extensively used to ball-mill blended elemental powders with large density or melting point differences, enabling production of nano-crystalline alloy and composite materials from a blend of elemental or alloy starting powders. Therefore, milling parameters such as milling time and rotation speed affect not only grain size but also the thermal stability of the as-milled alloy [12][13][14].…”

Magnetic multiresonance behavior of Fe@Al2O3 nanoembedments and microstructural evolution during mechanosynthesis

“…These nanocomposite powders have been prepared by directly milling of metal and ceramic powders [10,11], or by chemical methods involving the reduction in hydrogen of suitable oxide precursors [12]. The mechanosynthesis, or named as mechanochemical synthesis, has been attracting increasing interest in relation to the extensions of solid solubility [13], disordering of intermetallics, solid-state amorphization [14].…”
