Automated system for processing of PLZT powders derived from acetate precursors

An IBM-PC-based system for producing and controlling the production of PLZT (lead lanthanum zirconate titanate) powders from water-soluble acetate precursors is described. Problems with the development of appropriate sensing systems and algorithms are discussed. A proposed prototype system is presented. An automated batching system will be run by an expert system in such a manner in that when the desired composition of the PLZT acetate solution to be made is entered, the process will be changed to yield the correct amounts of each constituent needed.<
