摘要：

Isostatically pressed barium hexaferrite was sintered with constant heating rates to study the initial stages of sintering, and isothermally to study the intermediate stage. Due to the high rate of grain growth, the activation energy varies over a wide range and the coercive force drops rapidly. The higher the oxygen partial pressure the lower is the sinterability, implying that the diffusion of oxygen ion is the determining factor in the sintering process.
