Lithium mixed Potassium tetra titanates with 0.2, 0.4, 0.6, 0.8 and 1.0 molar percentage of LiCO (general formula KLiTiO) have prepared by a high temperature solid-state reaction route. The XRD results indicate that Lithium ions enter the unit cell maintaining the layered structure of solid solution. The crystals are monoclinic for x = 0.2, 0.4 and 0.6 while crystals are orthorhombic for x = 0.8 and 1.0 with a small change in ratio c/a in both cases. EPR analysis, The Lithium ions are accommodated with the Potassium ions in the interlayer space. The EPR spectra of Lithium mixed Potassium tetra titanates confirm the partial reduction of Ti ions to Ti.
