AI Technical Summary
Existing technologies make it difficult to prepare Ba3CaNb2O9 materials with regular micro-nano sheet structures at low temperatures and in a short time. Furthermore, traditional methods are energy-intensive, have long cycles, and produce products with large particle sizes and irregular morphologies.
The mixed molten salt method was adopted, in which a mixture of BaCO3, CaCO3, Nb2O5, NaCl and KCl was heat-treated in air atmosphere, with the heat treatment temperature controlled at 650-750℃ and the reaction time at 0.5-3h. After washing to remove the salt components, micro-nano sheet-like Ba3CaNb2O9 materials were obtained.
This method enables the rapid preparation of Ba3CaNb2O9 materials with regular sheet-like morphology at low temperatures, reducing energy consumption, simplifying operations, and making it suitable for large-scale production.
