PLZT ceramics production

Processing and Fabrication, Ceramics are traditionally prepared from powders formulated from the individual oxides however, early attempts to produce the PLZT powders by this method proved to be inadequate from the standpoint of chemical and optical uniformity. As a result, a chemical co-precipitation method designed specifically for the PLZT materials which utilized liquid precursor materials was developed and successfully implemented as a production process (15),... 

Chemical composition (and also material properties) could be modified to meet specific application needs by the addition of atoms of Nb, Sr, Fe, Mn, Cr etc. Special type of PZT ceramics is a La-doped PZT, commonly abbreviated as PLZT. Such ceramics is transparent, which could be controlled by the applied electric field. Chemical composition and manufacturing technology is usually proprietary know-how of each PZT manufacturer and it is not known to the end-users of PZT products.
