Summary

Starting with a submicron PLZT powder, produced by an improved mixed oxide route, transparent PLZT ceramics have been prepared by using cold pressed green bodies. Due to residual pores, the optical quality of these ceramics is strongly varying. Only about ten percent of the prepared samples show acceptable optical properties. Preparing the green bodies by electrophoretic deposition reduces the number and size of the pores significantly, leading to transparent ceramics with satisfying optical properties and a large decrease of the number of rejects. Alternatively, hot isostatic pressing was used to treat samples with residual porosity to improve their quality. It is possible to close the pores by this process, obtaining fully dense PLZT ceramics.
