High-temperature reactions of phenyl oxidation

Symposium (International) on Combustion, 1994
The reactions of phenyl radicals with molecular and atomic oxygen have been studied in the temperature range 900–1800 K behind reflected shocks. The total pressure ranged from 1.3 to 2.5 bar. Phenyl radicals were generated by the fast thermal decomposition of nitroso- or iodobenzene.

High Temperature Oxidation Modeling

ECS Meeting Abstracts, 2020
One of the most demanding properties for reliable high temperature structural materials is oxidation resistance. The transition from internal to external oxidation is often a basis for alloy design to slow down the oxidation process. While lots of experimental efforts have been devoted to investigating the transition, there is still a significant ...

High temperature oxidation of Co-Mn alloys

Corrosion Science, 1979
Abstract The oxidation of cobalt-manganese alloys in the range 0–45 wt%Mn corresponding to the stability of the α-phase of cobalt has been studied in the range 750–950°C as an example of binary alloys producing solid solution scales. The alloys oxidize according to a parabolic rate law with a rate constant intermediate between those of the pure ...

Oxidation in High Temperature Petrogenesis

American Journal of Science, 1961
A study has been made of a variety of metamorphic and magmatic rocks to determine how oxidative processes are reflected in their mineral assemblages. In this study particular attention is paid to solid solutions. Field and experimental evidence agree with theory as to the responses of ferromagnesian solid solution to compositional changes of the ...

High-temperature oxidation of rhodium

Oxidation of Metals, 1990
The oxidation kinetics of Rh were measured in air at 1 atm. in the temperature range 600–1000°C. The oxidation weight gain proceeds logarithmically at the lower temperatures (600°C, 650°C) followed by a transition to power law behavior at the higher temperatures (≥800°C). The logarithmic growth kinetics result from thickening of a hexagonal Rh2O3 scale.

High-Temperature Gaseous Oxidation

2009
So far this text has considered the corrosion of metals or alloys in aqueous environments. However, when a metal or alloy is exposed to an oxidizing gas, corrosion may occur in the absence of an electrolyte, especially at high temperatures. This phenomenon is sometimes called “dry corrosion” as opposed to “wet corrosion” which occurs in the presence of

High temperature oxidation of Ni2AlTi

Journal of Materials Science, 1989
The isothermal oxidation process in bulk and powdered Ni2AlTi (L21 structure) has been studied in the temperature range of 600 to 1200° C in air by means of X-ray diffraction and scanning electron microscopy. At 900 and 1200° C, the transient oxides, NiO and TiO2 were formed in the initial stage on the outer surface.

High temperature oxidation of acetaldehyde

Symposium (International) on Combustion, 1977
The gas phase kinetics of the first stage of acetaldehyde oxidation were studied from 1030°K to 1115°K in a turbulent flow reactor which permits accurate determination of the spatial distribution of stable species. Experiments were performed in nitrogen at atmospheric pressure containing 0.1–0.75% acetaldehyde and 0.16–8% oxygen.

High-temperature oxidation of ZrAl

Journal of the Less Common Metals, 1988
Abstract The oxidation of ZrAl in dry oxygen in the temperature range 800–1100 K follows a parabolic rate law. An activation energy of 86.4 kJ mol−1 was estimated. During the oxidation, aluminium diffuses from the oxide layer to the ZrAl bulk, thus forming a ZrAl2 phase very close to the oxide-alloy interface.

Oxide Electrodes at High Temperatures

1985
High temperature fuel cells and electrolysers based on solid yttria stabilized zirconia electrolytes typically operate at 1000°C to reduce polarization losses. Much of the published work on electrode reactions has been carried out on precious metal electrodes (1–4).
