Refinement of Electronic Ceramics by HIP

Abstract

ABSTRACTMnZn ferrites and PLZT with fine and uniform microstructures were prepared by hot isostatic pressing.Initial permeability of MnZn ferrites with grain size of 2.0 and 1.2 μ m was 600 at 10 MHz.An optical shutter array was made using PLZT with grain size of 2μ m. Optical transmittance was dependent upon the amount of PbO in HIP'ed PLZT. A slight deficiency of PbO in PLZT increased the transmittance at short wave length (400 nm).
