Abstract : Scanning electron microscopy (SEM) in conjunction with transmission electron microscopy (TEM) and optical microscopy was used to study the initial stages of the oxidation of high purity (111) and (110) Ta single crystals and large-grained 5 mil-thick sheet of approximately (001) orientation. Two different oxidation temperatures 530C and 800C were used as well as two different pressures, 1 atmosphere and typically 0.001 torr oxygen. (Author)
