Embodiment 1
[0018] The method for producing Potassium Fluoride of the present invention, is raw material with fluosilicic acid and Potassium Chloride, comprises the following steps:
[0019] (1) React 15% fluosilicic acid solution with potassium chloride solid for 30 minutes, filter to obtain potassium fluosilicate solid, and the liquid is waste hydrochloric acid; (2) put potassium fluosilicate at a temperature of 350°C, Decompose for 4 hours to generate potassium fluoride solid product and silicon tetrafluoride gas; (3) absorb and hydrolyze the obtained silicon tetrafluoride gas with water, filter to obtain a concentration of 15% fluosilicic acid solution and return to make fluosilicic acid Potassium, the resulting silica solids were washed and dried to obtain white carbon black.
Embodiment 2
[0021] The method for producing Potassium Fluoride of the present invention, is raw material with fluosilicic acid and Potassium Chloride, comprises the following steps:
[0022] (1) react 25% fluorosilicic acid solution with 30% potassium chloride solution for 30 minutes, filter to obtain potassium fluorosilicate solid, and the liquid is waste hydrochloric acid; (2) prepare the fluorosilicic acid Potassium decomposes at a temperature of 450° C. for 3 hours to generate potassium fluoride solid product and silicon tetrafluoride gas; (3) absorb and hydrolyze silicon tetrafluoride gas with water, and return the obtained 25% fluosilicic acid solution by filtration Potassium fluorosilicate is removed, the silica solid is washed and dried to obtain white carbon black.
Embodiment 3
[0024] The method for producing Potassium Fluoride of the present invention, is raw material with fluosilicic acid and Potassium Chloride, comprises the following steps:
[0025] (1) react 35% fluosilicic acid solution with 20% potassium chloride solution for 30 minutes, filter to obtain potassium fluosilicate solid, and the liquid is waste hydrochloric acid; (2) put potassium fluosilicate at 750°C Decompose for 2 hours to generate potassium fluoride solid product and silicon tetrafluoride gas; (3) absorb silicon tetrafluoride gas with water and hydrolyze, filter to obtain 35% fluosilicic acid solution and return to make potassium fluosilicate, silicon dioxide The solid was washed and dried to obtain white carbon black.
