Oxidation in Flow-Reaction Systems,-microbalance reaction systems are used to study the several chemical and physical mechanisms involved. To illustrate the method, the oxidation of rhenium and molybdenum is presented. Rates of oxidation of 10. atoms of Re or Mo were observed at 1100 and 1400 C, respectively. Comparison was made to p

The results of these studies provided useful information on the best precision and accuracy which can be achieved under different environmental conditions. Tests of reproducibility and linearity of response showed that accuracies of ±1

The amplitudes increased with increasing pressure and temperature difference between sample and beam. In a nitrogen atmosphere, the fluctuations began at 200 torr, and in an argon atmosphere at 140 torr, while in
