Effects of impurities on PZT ceramics

Journal Article:

Abstract

The grain growth, dielectric constants, piezoelectric properties, and resistivity of Pb(Zr/sub 0.52/ Ti/sub 0.48/)+0.008La/sub 2/O/sub 3/ (or Nb/sub 2/.O/sub 5/)+xFe/sub 2/O/sub 3/ ceramics have been investigated as a function of Fe/sub 2/O/sub 3/ content. The grain size decreases up to 0.05 (or 0.1) mole % Fe/sub 2/O/sub 3/, but increases in the further region. This can be interpreted as such that the grain growth is not retarded by those impurities when the Fe/sub 2/O/sub 3/ content approaches the La/sub 2/O/sub 3/ (or Nb/sub 2/O/sub 5/) content because of the formation of La/sup 3 +/ (or Nb/sup 5 +/)-Fe/sup 3 +/ ion pairs. The dielectric constant has a maximum at 0.2 mole % Fe/sub 2/O/sub 3/ and decreases as the Fe/sub 2/O/sub 3/ content increases from that composition. The grain size effect is dominant in the variation of dielectric constant up 0.2 mole % Fe/sub 2/O/sub 3/. The resistivity of the ceramics of which the Fe/sub 2/O/sub 3/ content is 0.8 mole % shows the same tendency as that of the pure PZT ceramics, and it can be concluded that complete compensation of the donor and the acceptor has occurred.
