Examples
Embodiment 1
[0013] In a connected reactor with 2 left and right ear grooves and 3 left, middle and right barrier plates, according to the molar ratio, manganese: phosphorus = 1: 1.50, manganese chloride is added to the left ear groove, and ammonium phosphate is added to the right ear in the slot. Then, a mixture solution containing 0.04% starch and 2.0% ammonium chloride by mass ratio is added to the connected reactor, so that the liquid level of the mixture solution of starch and ammonium chloride is higher than the left ear groove and the right ear groove The upper edge is 1 cm to ensure that the reactants in the left ear groove and the right ear groove are connected through the mixture solution. Finally, the lid was put on the connected reactor, and after 7 days of static reaction, the product was filtered, washed, and dried at 105° C. for 1 hour to obtain ammonium manganese phosphate crystals. The yield of ammonium manganese phosphate crystals was 98%, and the purity was 99.5%.
Embodiment 2
[0015] In a connected reactor with 2 left and right ear grooves and 3 left, middle and right barrier plates, according to the molar ratio, manganese: phosphorus = 1: 1.40, manganese chloride is added to the left ear groove, and ammonium phosphate is added to the right ear in the slot. Then, a mixture solution containing 0.03% starch and 2.5% ammonium chloride by mass ratio is added to the connected reactor, so that the liquid level of the mixture solution of starch and ammonium chloride is higher than the left ear groove and the right ear groove The upper edge is 1 cm to ensure that the reactants in the left ear groove and the right ear groove are connected through the mixture solution. Finally, the lid was put on the connected reactor, and after 7 days of static reaction, the product was filtered, washed, and dried at 105° C. for 1 hour to obtain ammonium manganese phosphate crystals. The yield of ammonium manganese phosphate crystals was 97%, and the purity was 99.9%.
Embodiment 3
[0017] In a connected reactor with 2 left and right ear grooves and 3 left, middle and right barrier plates, according to the molar ratio, manganese: phosphorus = 1: 1.60, manganese chloride is added to the left ear groove, and ammonium phosphate is added to the right ear in the slot. Then, a mixture solution containing 0.05% starch and 1.5% ammonium chloride by mass ratio is added to the connected reactor, so that the liquid level of the mixture solution of starch and ammonium chloride is higher than the left ear groove and the right ear groove The upper edge is 1 cm to ensure that the reactants in the left ear groove and the right ear groove are connected through the mixture solution. Finally, the lid was put on the connected reactor, and after 7 days of static reaction, the product was filtered, washed, and dried at 105° C. for 1 hour to obtain ammonium manganese phosphate crystals. The yield of ammonium manganese phosphate crystals was 99%, and the purity was 99.0%.
