In this paper the influence of tribophysical activation on non-isothermal sintering of barium titanate has been investigated. BaTiO3 Powders were tribophysically activated in a planetary ball mill for 0, 60 and 120 min., pressed and non-isothermally sintered up to 1380 degrees C. Dilatometric analysis was performed in air in the temperature range from room temperature to 1380 degrees C with heating rates of 10, 20 and 30 degrees C/min. The samples were analyzed by the X-ray powder diffraction method. Investigation of the morphology of microstructure constituents was performed using the scanning electron microsocopy method. With the purpose of optimizing technological parameters the results obtained by microstructure analysis were correlated with the results of quantitative dilatometric analysis.
