1. Preparação e caracterização de materiais ferroelétricos de composição Bi4Ti3O12 contendo Lantânio e Érbio / Synthesis and characterization of Bi4Ti3O12 ferroelectric materials containing Lanthanum and Erbium
This work describes a systematic study of the influence of the lanthanum atom addition in the Bi4Ti3O12 (BIT) phase and the erbium atom addition in the Bi3,25La0,75Ti3O12 (BLT075) phase in terms of their synthesis process and its structural, microstructural and electrical properties. Ceramics of nominal composition Bi4-xLaxTi3O12 (BLTx) with 0 x 2 mol% and B

2. Laser sintering and characterization of the compounds Bi4Ti3O12 and Bi4Ge3O12 / "Sinterização a laser e caracterização física dos compostos Bi4Ti3O12 e Bi4Ge3O12"
The goals of this work were the implantation and optimization of the laser sintering technique for ceramic bodies, the kinetic study of the process and the evaluation of the physical properties of the laser sintered compounds Bi4Ti3O12 and Bi4Ge3O12, compared to ceramics sintered in conventional furnace. The choice of the materials was based on their potenti
