Intrinsic Studies of Materials - Sintering Mechanisms of Defect Oxides

摘要

The report summarizes an investigation of the influence of deviations from stoichiometry on the sintering of the defect oxide, CoO. The eleven conclusions reached in this investigation are listed in this report and among them are: (1) CoO sinters according to volume diffusion kinetics in the initial and intermediate stages, (2) The sintering rate is increased with increasing oxygen partial pressure above 0.001 atmosphere, (3) The calculated volume diffusion coefficients lie between the tracer values for Co and O in single crystals.
