The effect of Nickel percentage on the dielectric properties of Bentonite
This paper reports on the systematic measurement and modelling of the impedance spectra in Bentonite support (solid pellets) with various Ni content (x = 0%, 1%, 3%, 5%, 7%, 13%, 15%, 17% and 20%) for the aim of investigating the dielectric loss tangent versus x. The extracted conductivity and loss...

| Summary: | This paper reports on the systematic measurement and modelling of the impedance spectra in Bentonite support (solid pellets) with various Ni content (x = 0%, 1%, 3%, 5%, 7%, 13%, 15%, 17% and 20%) for the aim of investigating the dielectric loss tangent versus x. The extracted conductivity and loss tangent exhibited nonlinear variations with x and only rapidly increased above x = 13%. This behavior is more pronounced at low frequencies <100 kHz and is qualitatively consistent with reports about the conductivity of metal–insulator mixture, suggesting better dispersion efficiency of Nickel on Bentonite. |
