Abstract

Preparation and Study the Structure of Pure and Impure Barium Titanate with Zr4+ Ion

Highlights

Barium titanate has been used in wide application such as capacitors and multilayer capacitors (MlCS) [1,2], PTC thermistors, piezoelectric transducers, variety of electro-optic devices and integral capacitors in printed circuit boards (PCB)
Pure and impure barium titanate was synthesized via solid-state reaction, pure barium titanate (BaTiO3)(BT) was synthesized by mixing raw materials barium carbonate BaCO3 with purity (98%) and titanium dioxide TiO2 with purity (98%) of molar ratio [1:1], add ethanol alcohol with purity (98%) in order to obtain good homogeneous, all mixture were mixed in ball
III X-ray diffraction of impure barium titanate (BZT) In this part additive zirconium oxide ZrO2 to the barium titanate with two molar ratios (5%, 10%) calcinations at two temperature (950°C and 1400°C) study the structure of barium titanate using x-ray diffraction after this additive, the additives of ZrO2 to barium titanate lead to change from tetragonal phase to cubic phase at 1400°C and an increase in lattice parameters [10], this is a clear refers to the addition of Zr lead to disorder in the barium titanate structure[11]

Summary

Introduction

Barium titanate has been used in wide application such as capacitors and multilayer capacitors (MlCS) [1,2], PTC thermistors, piezoelectric transducers, variety of electro-optic devices and integral capacitors in printed circuit boards (PCB). BaTiO3 is a semiconducting and non- linear optical material when doped with other elements, and can be used for resistors with a positive temperature coefficient of resistivity [3]
