Oxidation in High Temperature Petrogenesis
American Journal of Science, 1961A 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 ...

The high-temperature oxidation of aldehydes
Symposium (International) on Combustion, 1971Studies of the oxidation of aldehydes have given the velocity constants k1=0.013 and 0.076 liter mole−1 sec−1 for HCHO and C2H5CHO, respectively, and k4=1.36×106, 1.82×106, 2.41×106 liter mole−1 sec−1, for HCHO, C2H5CHO, and n-C3H7CHO, respectively, at 440°C, on the assumption that k5=1.8×109. These are preliminary values which may be modified slightly

High-temperature oxidation (HTO) of metals and alloys is a scale-forming oxidation process in gaseous environments. HTO is influenced by metal temperature, gas composition, exposure time, and pressure, and it may be characterized by weight gain, thickness reduction (penetration), and rate of oxide thickness growth, which is a measure of the rate of ...
