Abstract
The phenomenon of subparabolic oxide growth rate, more the rule than t he exception in the oxidation of silica formers, is examined in light of data sets acquired in SiC oxidation experiments at 1300 degrees C. Negative deviation from parabolic kinetics is shown to correlate with oxide crystallinity. The data sets were analyzed to ascertain the pred ominant and contributing growth laws, and tested with models that desc ribe the overall kinetics as combinations of the familiar growth laws.
