Udayraj C. Yadav; Yuvraj S. Malghe

Volume 2, Issue 11 , 2017, , Pages 729-733

  Nanosized barium cerate (BaCeO3) was prepared from barium cerium oxalate (BCO) precursor. Thermal decomposition of BCO precursor was studied using thermogravimetry(TG), differential thermal analysis (DTA), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) techniques. BCO precursor ...  Read More

Simplify the resolve of AC parameters such as immittances, conductivity and dielectric by using the delay-time measurement

Volume 2, Issue 10 , 2017, , Pages 615-620

  Our novelty for the presented work is to find a simple method to study electric and dielectric properties for samples such as magnetic materials. We focus on prepare and characterize of the ferrites. During the AC measurements, we struggled to use the Lissajous figure.  In addition, we have a shortage ...  Read More

AC conductivity and dielectric analysis of Pb1-xLax[(Mg1+x/3Nb2-x/3)0.65Ti0.35(1-x)/4]O3, (x = 0, 0.02, 0.05) relaxor ferroelecric ceramics

  In this paper we investigate the effect of lanthanum doping on structural, dielectric and electrical  properties  of lead magnesium niobate - lead titanate, 0.65Pb(Mg1/3Nb2/3O3)- 0.35PbTiO3 (x=0, 0.02, 0.05) ferroelectric ceramics. Dielectric and AC impedance spectroscopic measurements were ...  Read More

High Dielectric Constant SiO2 Nanoparticles

Sathosh K. Kurni; Pradip Paik

Volume 1, Issue 1 , 2016, , Pages 114-117

  SiO2 nanoparticles of average size 15-20 nm have been synthesized and its dielectric properties have been investigated as a function of frequency (between 20 Hz to 2 MHz). A very high dielectric constant of ca. 14000 at 20 Hz and at room temperature has been observed which is very high compared to the ...  Read More
