OXIDATION OF ZIRCONIUM AND ZIRCONIUM ALLOYS [PDF]

open access: yesJournal of The Electrochemical Society, 1959
Zirconium oxidation was investigaied in the temperature range 400 io 900 deg C at oxygen pressures of 50, 200, and 800 mm. The reaction rate of massive (parallelepiped) samples was best expressed by the cubic rate law. At an oxygen pressure of 200 mm the activation energy was calculated to be 42.7 kcal per mole, and the cubic rate constant in ( mu g ...
