Abstract: The optimization of the sintering temperatures of dielectric materials such as barium titanate (BaTiO₃) and lithium niobate (LiNbO₃) in the form of pelletted ceramics has been reported. The optimized temperature for BaTiO₃ is 950ºC and in the case of LiNbO₃, it is 900ºC based on the temperature optimization studies carried out in the temperature range 800-1000ºC. The crystallanity nature has symmetrically been analyzed through the XRD and FTIR spectral measurements. Crystallization nature of the materials has been found to be tetragonal based on the XRD data results. Such tetragonal crystalline natured dielectric materials are of technological importance and significant relevance in the progress of wide variety of opto-electronic materials.
