Kinetics of the High Temperature Oxidation of Zi rcon ium I

The rate of oxidation of high purity zirconium was determined for the temperature r,~nge of 575 ~ to 950 ~ at 1 arm pressure. Data can be fitted to a cubic law and the rate constant in (ml/cm~)3/sec has been calculated to be k = 3.9 X 106 e-47,2~176 where 47,200 • 1,000 cal/mole is the activation energy for the reaction
