Barium-calcium-silicon series composite nano-ceramic powder and preparation method thereof
A preparation method for a barium-calcium-silicon series composite nano-ceramic powder comprises the following steps: weighing a barium-calcium-silicon precursor according to the stoichiometric ratio of BaxCa1-xSiO3 (x=0-1); weighing a certain amount of NaCl or KCl as a molten salt medium; putting the molten salt medium and the barium-calcium-silicon precursor into a mixing tank for wet-process mixing, and drying; putting the dried materials in an electric furnace for heat processing; and performing washing and filtering on the material subjected to heat processing, and drying the filter cake, so as to obtain the composite nano-ceramic powder. According to the preparation method for the barium-calcium-silicon series composite nano-ceramic powder, the raw materials are cheap and easy to obtain, the washed-off molten salt is reusable after being recrystallized, and the technology is simple and is suitable for large-scale production.
