| Outline of Final Research Achievements |
This study developed the novel self-pulverisation oxides and elucidated the self-pulverisation mechanism. The results based on XRD, SEM, and EDX demonstrated that a small amount of excessive LaCoO3 mixed in oxides hydroxylates with a significant volume expansion, eventually causing the pulverisation of oxides. The local stress distribution and critical crack length around excessive LaCoO3 particles are estimated. Various conventional ceramics were successfully pulverised by controlling the excessive amount of LaCoO3 and the atmosphere.
