Nghiên cứu tổng hợp vật liệu BaTiO3 kích cỡ nano bằng phương pháp thủy nhiệt

Abstract

The BaTiO₃ powders were synthetized by the hydrothermal method in the alkaline solution using the TiCl₃ and BaCl₂ like precursors. The Ba/Ti initial ratios effect on the formation of BaTiO₃ phase was investigeted versus time (at 150°C). The results showed that BaTiO₃ powders have right stoichiometric (approximate 1), homogeneous morphology and grain sizes are in the range of 80 - 100 nm.
