Model No:FDD-10
Barium Titanate, BaTiO , is a well known and widely investigated dielectric material. It is mainly used in capacitors due to its high dielectric constant. The dielectric properties of BaTiO are controlled by purity and microstructure which are dependent on the methods of preparation. The ability of the dielectric material to store energy is attributed to the polarization which can result in an increase in capacitance. It is well known that dielectric properties of every solid are very sensitive to the local electric field distribution in the sample. The temperature and frequency dependence of dielectric constant and loss can therefore give useful information about structure changes, transport mechanism and defect behaviour of a solid.
The present experiment is designed to study the variation of capacitance and dielectric losses as a function of frequency and hence compute the change in dielectric constant, and loss factor, tan with frequency.
While the behaviour of Barium Titanate is distinctly frequency dependent, the performance of a standard multi layer ceramic capacitor (MLCC) and conventional ceramic capacitors are not as prominent. A comparison of these three therefore is an interesting part of the study.
