| titleOfInvention | Separation method of silicon carbide and silicon (1) |
| abstract | A method for separating silicon carbide and silicon includes a pretreatment step, a dispersion step, a pH adjustment step, a collection step, a mixing step, a standing step, a centrifugation step, and a drying step. The present invention can separate the silicon carbide and silicon in the silicon wafer cutting waste by using a less toxic organic solvent, and by first adjusting the target acid-base value, and then adding a trapping agent to separate the silicon carbide and silicon One separation operation procedure can be achieved, and high-recovery silicon carbide and high-grade silicon can be obtained under the best separation conditions, and the separation efficiency of silicon carbide is more than 70%, and it can also separate particles below 10 μm, thereby reducing production The cost of waste disposal of solar cells and achieve the goal of circular economy. |
