[0024] Steps of the present invention:
[0025] (1) Weigh the raw materials barium nitrate and hydroxylamine sulfate according to the ratio of 1:1, and pour them into suitable three-necked bottles and beakers respectively;
[0026] (2) According to the ratio of adding 1500ml-2500ml distilled water per mole of barium nitrate, add an appropriate amount of distilled water into the three-necked bottle, raise the temperature to 60°C-70°C, and keep stirring until the barium nitrate is completely dissolved;
[0027] (3) According to the proportion of adding 500ml-1000ml distilled water per mole of HAS, add an appropriate amount of distilled water into the beaker, and keep stirring at room temperature until HAS is completely dissolved;
[0028] (4) Add the HAS aqueous solution to the barium nitrate aqueous solution at a rate of 1 drop / second to 3 drops / second, and the reaction system is always maintained at 60°C to 70°C. After the HAS aqueous solution is added dropwise, continue to m...
