Results show that under the same conditions, anion diffusion is significantly faster than cation diffusion. The results are discussed in terms of their implications for the reactive element effect on high temperature oxidation of chromia forming alloys.doi:10.1557/proc-122-193...
Using chromium oxide formed in aqueous solution as an example, the Mott-Schottky technique can identify the p-type characteristics and its population34, but it is impossible to tell whether the predominant point defect type is cation vacancies or anion interstitials as both are charged compensated ...
methyl, CH3, and I adatoms on 伪-Cr2O3(0001).The primary reaction of methyl is rate-limiting dehydrogenation to methylene, followed by methylene coupling to ethylene, CH2=CH2, or methyl hydrogenation to methane.XPS and DFT indicate that methyl species bind at both surface cation and anion ...
and the interconnect by limiting the growth of the Cr-based oxide scale. The material selected for the protection layer should exhibit high electrical conductivity coupled with low chromium cation diffusivity. Low oxygen ion diffusivity is also required to limit oxidation of the substrate alloy and ...
Computer-modelling techniques are applied to the calculation of defect formation and migration energies in α-Fe 2 O 3 and α-Cr 2 O 3 : both electronic and lattice defects are considered. The results are used to predict Arrhenius energies for cation and anion migration in different composition...
The cation-exchange resin-based sample is more active, due apparently to the smaller accessible titania surfaces in the anion-exchange resin-based sample as a result of the formation of a solid Ti3+ solution in 伪-Cr2O3.doi:10.1134/S2070050423030029Buzaev A. A....
is treated as a marker, then it may be assumed that the thinner outer layer grew due to the outward diffusion of metal via point defects in the cation sublattice, while the thicker inner layer formed as a result of the inward diffusion of oxygen via point defects in the anion sublattice...
