|Title:||The B-site order-disorder transformation in Pb(Sc 1/2Ta 1/2)O 3 triggered by mechanical activation||Authors:||Xingsen, G.
|Issue Date:||Aug-2004||Citation:||Xingsen, G.,Xue, J.,Wang, J. (2004-08). The B-site order-disorder transformation in Pb(Sc 1/2Ta 1/2)O 3 triggered by mechanical activation.

B-site disorder in Pb(Sc 1/2Ta 1/2)O 3 (PST) which is traditionally tailored by thermal annealing after sintering at elevated temperatures, can be triggered by mechanical activation. The B-site disorder in Pb(Sc 1/2Ta 1/2)O 3 triggered by mechanical activation can well be retained in sintered Pb(Sc 1/2Ta 1/2)O 3, leading to an unique ferroelectric transition behavior (e.g., from a normal ferroelectric to relaxor) and a shift in the Curie temperature. © 2004 Kluwer Academic Publishers.||Source Title:||Journal of Materials Science||URI:||http://scholarbank.nus.edu.sg/handle/10635/107315||ISSN:||00222461||DOI:||10.1023/B:JMSC.0000039225.87405.62|
