Abstract : PZT/polymer composites and a simplified method of their fabrication are described. Commercially available PZT Pb(Zr, Ti)03 powder is thoroughly mixed with a binder such as polyvinylalcohol and polymethyl methacrylate (PMM) spheres and pressed into pellets. The binder and PMM spheres are burnt out by heating pellets slowly and the porous pellets so obtained are sintered by heating them in closed high-purity alumina crucibles and lead zirconate as a source of lead is added thereto. The highly porous pellets thus obtained are impregnated with a suitable polymer such as silicone rubber elastomer or vinylcyclohexene dioxide epoxy. (Author)
