Nano particles of barium titanium oxide nanoparticle was synthesized and analyzing the structural and electrical parameters of the prepared samples by microwave assisted solvothermal method by microwave oven. Powder X-ray diffraction of the powder was carried out after calcinating the temperature 400oC resulted in. Pure monoclinic structure Ba2TiO4 nanoparticles was obtained with lattice parameters, a=6.1458 Ao, b =7.6727Ao, c=10.5673 Ao The particle size was obtained from the studies of X-ray line bordening studies and scanning electron microscopy studies was taken. The electrical parameters were found for Ba2TiO4 at 100 Hz to 1 MHz.
