Investigation of approaches to the BaTiO$_3$ piezoceramics production: the influence of the shaping method and the powder particles size

For the first time, the possibility of obtaining samples of BaTiO$_3$ piezoceramics with $d_{33}$ values between 240–270 pC/N from commercially available powder by vibrational pressing (vibropressing) and semi-dry pressing without the use of expensive methods of doping and/or alloying the initial powder and texturing piezoceramics is shown. The method of vibropressing with a pressure of 10 MPa allows to get similar structure and properties of samples, as well as the method of semi-dry pressing with a pressure of 100 MPa.
