The fabrication of the barium titanate ceramic capcitors has been studied. The effects of the impurities for alumina and silica upon mechanical and electrical characteristics have been examined in detail. The preparation of equimolar titanium oxide and barium carbide in addition two percent of alumina and point two five perdcent of silica has shown the best results. This is fired up to thirteen hundred degrees Celsius with the rate of two hundred degrees Celsius per hour and soaked three hous at this temperature. The dielectric constant of this sample is approximately equal with the standard and theoretical values at room temperature. The insulation resitances of the most fabricated capacitors are in the order of twenty thousand megohms, the dielectric constant and the dissipation factor are almost flat up to just below of curie temperature, and the porosities of the most ceramics are less than point one percent and well close or equal to zero percent.
