Thermodynamic Benefit of Abnormal Grain Growth in Pore Elimination During Sintering

Thermodynamic Benefit of Abnormal Grain Growth in Pore Elimination During Sintering

Free‐energy analyses performed on closed particle‐pore arrays show that the presence of an abnormal grain thermodynamically favors the shrinkage of large pores to which is is adjacent. This gives an explanation to the experimentally observed phenomenon of abnormal‐grain‐growth‐promoted densification...

Zusammenfassung:Free‐energy analyses performed on closed particle‐pore arrays show that the presence of an abnormal grain thermodynamically favors the shrinkage of large pores to which is is adjacent. This gives an explanation to the experimentally observed phenomenon of abnormal‐grain‐growth‐promoted densification in barium titanate.
