Hot Isostatic Pressing of PZT and PLZT Ceramics

Abstract

This paper provides an overview of the method of hot isostatic pressure treatment of lead-zirconate-titanate (PZT) and lead-lanthanum-zirconate-titanate (PLZT) ceramics. Densified PZT ceramics are useful for miniaturized electronic components. PLZT ceramics sintered by HIP exhibit a high transmittance spectrum without serious growth of crystal grains. These microscopically uniform PLZT ceramics are a response to demands for good machinability, and will be the best candidate for optical micro-shutters for electrophotographic printers, in which switching time in micro-seconds is required.
