ABSTRACT

Barium titanate ceramic samples were synthesized from mixture of TiO₂+BaCO₃ under influence of concentrated light flux of 200 Wt/cm² at 2000℃ followed by quenching (A-type) and by the ceramic technology at 1350℃ followed by cooling at the rate of 100℃/min (B-type). The both types of samples had tetragonal symmetry lattice with the parameters a=0.399 nm and c=0.403 nm, however their tetragonality degree 未 = c/a 鈥� 1 slightly differed (0.01 and 0.007 for A- and B-type, respectively). Dielectric permittivity value was 3800 for A-type and 3400 for B-type; bending deformation began at 66 MPa for A-type and 49 MPa for B-type.
