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.
