Abstract:Through improving preparation process and modifying the composition, the excellent PMN-based electristrictive ceramics with a formula of (1- y )[(1- x )PMN- x PT]- y WO 3 have been prepared. The effects of additives on the properties and the relationship between the electristrictive properties and microstructure of the ceramics were discussed in the present work.
Keywords:PMN-based ceramics electristrictive ceramics electristrictive relaxation
