Abstract

The study of electrical properties of composite ceramics based on lithium ferrite LiFe5O8 with the addition of ZrO2 (1 and 2 wt%) was carried out. The samples were prepared by standard ceramic technology. Synthesis of lithium ferrite was conducted at 800°C for 120 minutes. The zirconium dioxide was added to synthesized powder by mixing in planetary ball mill, and then the composite powders were sintered at temperatures of 1100°C and 1050°C. The electrical conductivity of the samples was studied using two-probe spreading resistance method. It was found that addition of ZrO2 and an increase of its up to 2 wt% leads to increase in the activation energy and electrical resistivity.
