Fabrication of Mn Doped PZT for Ceramic-Polymer Composites

Abstract

Lead zirconate titanate (PZT) ceramics, with general chemical formula Pb(Zr 1−x Ti x )O 3 are used in numerous piezo-and pyroelectric applications. In practice, PZT is rarely used in a chemical pure form. The dielectric, piezoelectric and pyroelectric properties of PZT can be modified by adding dopants to the ABO 3 -type PZT perovskite structure.Ceramics powders of manganese-doped lead zirconate titanate with composition Pb(Zr 0.3 Ti 0.7 ) 0.97 Mn 0.03 O 3 (PMZT) were prepared by the sol-gel method using: lead(II)acetate trihydrate, zirconium(IV)propoxide, titanium(IV)propoxide and manganese(II)acetate tetrahydrate as precursors. The PMZT-PVC composites were fabricated from PMZT and polymer powders by hot-pressing method.Keywords: ceramic-polymer composites, PZT+Mn, sol-gel Ceramiczne roztwory stałe cyrkonianu tytanianu ołowiu (PZT) o wzorze ogólnym Pb(Zr 1−x Ti x )O 3 znajdują szerokie zastosowanie jako piezo-i piroelektryki. W praktyce czysty PZT jest rzadko używany. Właściwości piezoelektryczne i piroelektryczne PZT modyfikuje się poprzez dodawanie domieszek do struktury typu perowskitu ABO 3 .Ceramiczne proszki cyrkonianu tytanianu ołowiu domieszkowanego manganem o składzie Pb(Zr 0,3 Ti 0,7 ) 0,97 Mn 0,03 O 3 (PMZT) otrzymano metodą zolowo-żelową. Jako prekursorów użyto: octanu ołowiu, propanolanu cyrkonu, propanolanu tytanu i octanu manganu.Kompozyty ceramiczno-polimerowe PMZT-PVC otrzymano z proszku PMZT i proszku polimeru PVC metodą prasowania na gorąco.

“…A possibility to use a piezoelectric ceramics in the electronic industry, in micromechatronics [1], electroacoustics or to build elements of medical equipment is conditioned mainly by stability of its mechanical and electric parameters [2][3][4][5]. One of the most interesting materials for use in micromechatronics is a multicomponent solid solution PZT-type with perovskite structure [6][7][8][9].…”

Energy Harvesting Based on a Novel Piezoelectric 0.7PbZn0.3Ti0.7O3-0.3Na2TiO3 Nanogenerator

“…The common conventional methods of piezoelectric material preparation are the solid-state method [2,3] and wet chemical methods such as the hydrothermal method and the solution gel (Sol-Gel) method [4]. Wet chemical methods are carried out at lower temperatures and hence became more attractive, especially for the nanogenerator harvesters.…”

Internal friction phenomena in composites based on PZT-type ferroelectric powder and ferrites

“…In order to broaden the application possibilities of composite materials obtained based on PZT-type ferroelectric powder and ferrites, it is necessary to learn their physical, chemical and mechanical properties, as well as their actual structure [1,2]. Knowledge regarding the relation between the chemical composition, crystalline structure and electro-physical properties allows for obtaining this type of materials with increasingly better and more stable properties, necessary for functional application in modern technology.…”
