Abstract

 

ZnxCoyO4 spinel samples were made using the thermal ceramic method, with (x = 0.2, 0.4, 0.6, and 0.8) as the molar ratios for samples. The molecular weights of the main compounds were used to determine the necessary weights of each material. The samples were sintered for 30 hours at 450oC after the doping and heating processes were completed at the selected molar ratios and within the temperature range of 25–450oC. Within the frequency range of 5Hz-1MHz, the electrical parameters of the resultant samples were diagnosed and quantified. These properties included electrical conductivity σ, electrical capacitance C, relative dielectric constant Ԑr, and loss tangent tanδ. The findings demonstrated that, with respect to the variation in the percentage of zinc (Zn) in the samples, the highest electrical conductivity value is 5.50×10+4 (Ω.cm)-1, the highest value of C is 84.57 pF, the highest Ԑr value is 190.58, and the lowest value of tanδ is 2.34×10+6.
