METHOD OF FORMING nanocrystalline powders Y1-xBaxFeO3 sol-gel method

摘要

A method of forming nanocrystalline powders YBaFeOzol-gel method comprising boiling the raw material solution for 5 minutes, where the starting materials used ferric nitrate and yttrium compound and a dopant, cooling the solution to room temperature, add dropwise with stirring a precipitant solution in an amount necessary for complete precipitation of cations, stirring at 3000 rev / min for 15 minutes, filtering, washing and drying the resulting precipitate at room temperature until constant second mass; calcining the precipitate in a muffle furnace; characterized in that the dopant used barium Ba, as compounds of yttrium and dopant used their nitrates, and starting materials were used at the following concentrations: 0.008 × (1-x) MY (NO), 0.008 × xM Ba (NO), wherein x - degree of doping x≤0.1, 0.008 M Fe (NO), as a precipitant solution, an aqueous sodium carbonate solution, and calcining the precipitate was conducted in a muffle furnace at 750 ° C for 60 min.
