Spark-plasma-sintering (SPS) process uses a microscopic electrical discharge between sintered particles under pressure. BaTiO3 samples were manufactured using SPS process at sintering temperature 1300°C, pressure 80 MPa, sintering time 20 min and controlled cooling rate. Dielectric properties of BaTiO3 samples were measured in the frequency range from 9 kHz to 1 MHz. Measured samples exhibit extremely high value of relative permittivity and anisotropy of dielectric properties.
