摘要：

This work reports the synthesis and electrical characterization of Bi4Ti3O12 ceramics produced successfully by a new method based on a CO2 laser sintering process. The structural and microstructural characterizations revealed that this method is able to produce sintered samples with high quality, free from secondary phases and with density as high as 98% of the theoretical one. Additionally, ferroelectric and dielectric investigations also revealed excellent values for the polarization and dielectric constant, respectively, thus showing the viability of the proposed method.
