Investigations of the effect of the morphology of Nb dopant on lead zirconate ceramic

PDF Version Also Available for Download.

Description

The microstructures of ferroelectric ceramics are a result of the dopants and of the many process variables associated with raw materials, powder processing, and ceramic firing. Metal ion substitutions of higher than normal valency are used as sintering aids to promote densification, to increase electrical resistivity, and to develop mature homogeneous microstructures with desirable piezoelectric and ferroelectric properties. Investigations are reported for the barium modified lead zirconate system which is analogous to the lead zirconate titanate system, in which Nb is used as a sintering aid. The morphology and concentration of the Nb are shown to affect both electrical properties ... continued below
