Paper Title:
Difference in Ordering Ability Between Ca(Al1/2Nb1/2)O3 and Ca(Fe1/2Nb1/2)O3
  Abstract

Ca(Al1/2Nb1/2)O3 (CAN) and Ca(Fe1/2Nb1/2)O3 (CFN) were prepared by solid reaction route. With the sintering temperature increased, the Q×f value of CAN changes from 7 200 to 17 500 GHz due to the changing of the ordering degree, whereas, the dielectric constant and Q×f value of CFN decrease remarkably without structural changing. The reason of this phenomenon is that the difference in size of two B-site ions in CAN is larger than that in CFN. As a result, the ordering degree of CAN is more sensitive to the conditions of sample preparation, compared with CFN.
