| Abstract Scope |
The present investigation shows the advances in the synthesis of BaTiO3 (BT) by the hydrothermal method. Two experiments were carried out; in the first one, the reactor was cooled in a controlled way until reaching room temperature, and in the second experiment, the reactor, after 24 h of synthesis inside the furnace, was cooled suddenly. As a result, variations were observed in the particle sizes of both experiments, obtaining the smallest size, 267 nm, cooling the powders; while the powders cooled in a controlled manner, the size increased, 452 nm, and presented 2 groups of size distribution. XRD analysis showed no evidence of secondary phase formation, only the desired BT phase; on the other hand, SEM images allow us to distinguish the morphologies depending on the cooling rate. Raman spectroscopy studies reveal the stability of the tetragonal phase after sintering. |
