In this present study, the Titanium phosphates (TiP 2 O 7 ) and Lithium titanium phosphate (LiTiP 2 O 7 ) materials were synthesized by using soft hydrothermal method at moderate pressure and temperature conditions. The resultant materials were characterized by using P-XRD, SEM, EDAX, FTIR, TGA, DSC and Electrochemical impedance spectra (EIS). From P-XRD, confirms the well crystalline rhombohedral phase and was found to be in the range below 100 nm. FTIR spectra indicated that there is an increase in the degree of splitting and stretching of the vibration bands, whereas the splitting of vibration bands and polymerization of [PO 4 ] decreased as the Ti ions. The TGA/DSC studies revealed that, these materials display endothermic reactions due to the liberation of ligands and diffusion. Thermal stability of the materials improved and the dielectric constant decreases. AC conductivity measurements for both the samples were carried and results are plotted. From AC conductivity studies, it is observed that the ionic conductivity of dc conductance of sample was measured show the frequency dependence dc capacitance of LiTiP 2 O 7 material. The frequency response dc capacitance also depends on doping with titanium.

The main objective of the present study was to synthesis the different immobilization of Sr +2 in LiSr 2 (PO 4) 3 crystals using soft hydrothermal method at moderate pressure and temperature conditions.The powder X-ray diffraction confirms that, the synthesized LiSr 2 (PO 4) 3 material has very good phase purity and crystalline with rhombohedralstructure.The energy-disperse X-ray (EDX) spectroscopic analysis shows their elemental composition correlating well with that of the strontium.Observation through a Scanning Electron Microscope (SEM) shows that microstructures of good quality and exhibited smooth surface, sub transparent and sub vitreous lustre. The FTIR studies was used to determine whether the bond structures were affected from the doping or not and revealed that the presence of O-H molecules and minute structural variations of synthesized materials.The TGA graph, temperature vs. weight % loss decreases with increasing the temperature showsLithium strontium phosphateas thermally stable so it is used as some optoelectronic device applications.The electrical conductivity of LiSr 2 (PO 4) 3 was investigated as a function of the nature of the transition-metal cation. Impedancemeasurementshow that the materials have relatively good ionic conductance.
