Pure and nickel doped (x = 0.05, 0.10, 0.15 mol%) polycrystalline potassium hexatitanate (K2Ti6O13) ceramics were synthesized using conventional solid state reaction route. Lattice constants have been evaluated from XRD data recorded at Room Temperature (RT), revealed its single phase formation in a monoclinic symmetry. XRD result corroborated the successful doping of Ni in the K2Ti6O13 matrix. Dielectric and electrical properties (relative permittivity ε, loss tangent tanδ and ac conductivity σac) have also been studied as a function of frequency at room temperature for all specimens and it is found that these parameters generally decrease with increase in frequency and dopant concentration.
