摘要：

A tracer sectioning technique was used to measure cation self‐diffusion coefficients in fully dense polycrystalline YaO3 and Er2Os under oxidizing conditions. The results are described by the relations (Formula Presented.) for Y2O3 (1400° to 1670°C), and (Formula Presented.) for Er2O3 (1400° to 1700°C). The greater activation energy for erbium diffusion in erbia may be partly attributable to a mass effect. Copyright © 1969, Wiley Blackwell. All rights reserved
