Difference in Ordering Ability Between Ca(Al1/2Nb1/2)O3 and Ca(Fe1/2Nb1/2)O3

摘要：

　　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×fvalue of CAN changes from 7 200 to 17 500 GHz due to the changing of the ordering degree,whereas,the dielectric constant and Q×fvalue 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.
