Ultrahigh Degree of Cationic Disorder, Configurational Entropy in New Type of High‐Entropy Pseudobrookite Phase

Jinyu Wu, JinFeng Zhang, Xiaoxia Hu, Haijiao Xie, more

Small > 20 > 26 > n/a - n/a

High‐entropy ceramics exhibit various excellent properties owing to their high configurational entropy, which is caused by multi‐principal elements sharing one lattice site. The configurational entropy will further increase significantly if multi‐principal elements randomly share two different lattice sites. For this purpose, pseudobrookite phase containing two cationic lattice sites (A and B sites)...
