Abstract
The research aims to investigate influences of annealing on the electrical properties of Ba0,5Sr0,5TiO3. Ba0,5Sr0,5TiO3 material which was annealed at 900°C for 1, 2 and 4 hours has better mechanical properties. It needs investigation for its electrical contribution, namely the correlation between grain and grain boundaries to values of resistance and capacitance. The changing of electrical properties was controlled by grain, grain boundary and the area between the sample and contact. The electrical properties of Ba0,5Sr0,5TiO3 were investigated by impedance spectroscopy in the room temperature. This method is able to separate the electrical and dielectric properties of the grain, grain boundary and the area between contact with the sample. ZsimpWin software was used to find out the equivalent electrical circuit, the resistance and capacitance value. It was observed that with the increase in annealing time the small grains resistance, the grain boundaries resistance, and the large grain capacitance value also increases. The resistance values of small grains and large grains were smaller than the grain boundaries resistance. The value of capacitance-resistance of the small grains and large grains were obtained values that tend to be smaller.
Highlights
The rapid development and advancement of technology were influenced by the development of material as its basic material
Volume 1, Issue 1, pages 23–32 ISSN 2655-8564 increasing in annealing time will increase the Zreal value
It indicates that Zreal at high frequencies, grains contribute to electrical conduction, while at low frequencies the role is at the grain boundary
Summary
The rapid development and advancement of technology were influenced by the development of material as its basic material. The development of the material certainly is inseparable from the development of discoveries of properties superior of a material as its basic material [1]. Solid materials have been conveniently grouped into three basic categories: metals, ceramics, and polymers, a scheme based primarily on chemical makeup and atomic structure. Most materials fall into one distinct grouping or another. A brief explanation of these material classifications and representative characteristics is offered next. A brief explanation of these material classifications and representative characteristics is offered Another category is advanced materials— those used in high-technology applications, such as semiconductors, biomaterials, smart materials, and nanoengineered materials [1]
