The cobalt-indium system: enthalpy of formation and phase diagram

Self-organized spatio-temporal micropatterning in ferromagnetic Co–In films

“…Nevertheless, the calculated equilibrium phase diagram of the Co + In system establishes the coexistence of hcp-Co and CoIn 2 phases at room temperature for Co percentages $33.3 at%. 18 Interestingly, the monoclinic CoIn 2 phase is not detected in our diffractograms, but only the ordered tetragonal CoGa 3type CoIn 3 forms, in concordance with a previous study on the electrodeposition of Co-In. 12 It has been claimed that CoIn 3 is one of the phases forming the spatio-temporal patterns.…”

“…According to its phase diagram, In and Co are immiscible in both solid and liquid states. 18 Hence, the formation of multi-phase coatings is anticipated. Energy dispersive X-ray (EDX) mapping analyses of the Co-In lms have been conducted in order to explore the chemical composition of the spatio-temporal patterns.…”

Efficient CO2 conversion to CO using chemical looping over Co–In oxide

“…However, Co–In 2 O 3 also achieved a high maximum CO 2 conversion of 70–80% in the medium temperature region, while suppressing the melting of indium because the redox of indium progresses with the formation and decomposition of Co–In alloy (as discussed later) with a high melting point. 28 To summarize the discussion presented above, Co–In 2 O 3 can improve the redox kinetics of indium and can achieve high stability, while maintaining the maximum CO 2 conversion. Additionally, compared to materials reported earlier, Co–In 2 O 3 has higher performance and is an industrially more promising material.…”

Spontaneous formation of spiral-like patterns with distinct periodic physical properties by confined electrodeposition of Co-In disks

“…Typically, spatio-temporal structures form at sufficiently negative applied current densities (large Co contents). Since In and Co are immiscible in both solid and liquid states 29 , the formation of multi-phase coatings is indeed anticipated. Remarkably, we have recently demonstrated that topographic and compositional spatio-temporal patterning in electrodeposited Co-In films induces a concomitant periodic change of the surface physical properties 26 .…”
