Influence of potassium doping on the structural, conduction mechanism, and dielectric properties of CaFeO.

The frequency and temperature-related dielectric relaxation and electrical conduction mechanisms in potassium-doped CaFeO oxide ceramic were investigated in this study throughout a temperature range of 313-673 K. The synthesis of the KCaFeO compound was accomplished through a solid-state reaction route. The X-ray diffraction pattern at room temperature confirmed that the ceramic KCaFeO crystallizes in the orthorhombic system with the space group.
