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.

镍含量对膨润土介电性能的影响

本文报告了各种镍含量(x  = 0%,1%,3%,5%,7%,13%,15%,17%)的膨润土载体(固体颗粒)中阻抗谱的系统测量和建模和20%)以研究介电损耗正切与x的关系。提取的电导率和损耗角正切随x呈现非线性变化,并且仅在x  = 13%以上时迅速增加。这种现象在<100 kHz的低频下更为明显,并且在质量上与有关金属-绝缘体混合物电导率的报道一致,这表明镍在膨润土上的分散效率更高。
