摘要
Strontium modified (SrBi4Ti4O15) and "pure" bismuth titanate (Bi4Ti3O12), were prepared by ordinary firing (OF) and hot forging (HF). Samples with grain oriented (F>0.90) were obtained after hot forging. Ferroelectric, dielectric and piezoelectric characterizations reveal that polarization reorientation is restricted to the planes of the platelike grains.
